How Can Technology Help the Environment?

How can technology help improve the environment? Are we promoting a more singular existence, where individualism is the force that is driving us along? We are now living in a world that is in an accelerated mode of change and innovation. Is this rate of change detrimental to our existence? Think about this for a moment. On the one hand we have improvements in all areas of our lives some are greater than others. On the other hand we are looking at the effects of the harmful destruction of our planet earth.

The first computers started to emerge around the 1940’s, now we have computer processors in a lot of the electronic equipment we use every day. We even have computers that can fit in your hand that have more power than the first computers.The first Television and television transmission appeared in 1925 and now we are watching gigantic flat screens, some as big as buildings and others screens as small as wrist watches. In the past 80 years the medical field has also grown in leaps and bounds in the areas of IVF, genetic research, cloning, stem cell research, along with the progress in the prevention, cure and management of various diseases. Other fields such as astronomy, environmental science, weapons/warfare and engineering have also had their fair share of extraordinary development achievements.

Looking at the issues of Global warming and human environment interaction we are currently facing within our natural environment. Should we really be in a race to ruin the land where we live? We cannot keep up with the current technology, just look at all the equipment you have taken to the recycle tip in just the last 12-24 months. Consider how many Televisions, Videos, DVD players, Computers, Laptops, Hi-fi’s and Home entertainment systems you have changed or bought recently, the list is endless. When an improvement is made to a product it can sometimes make the original product obsolete. Satellite Navigation equipment a new and easily available product for everyone. Even if you only use it once a year it is believed to be a must have product. Mobile phones is another product every man and his dog has one these days. How often do you change your mobile phone for the latest model? Can you ever imagine being without a mobile phone? How did we ever cope without them? The raw materials used to make a phone cannot be recycled easily. 

I believe as we get to understand one part(s) of our lives we seem to lose sight of others parts that are equally as important. What can be done to slow down the rate of change or how do we as a nation become more aware of the effects of the rate of change has on our environment.

If we could not have a new television or other new product until the old one had been recycled properly we would help the environment tremendously. Today if we implemented this many products or versions of products would be missed because of the speed at which technology changes. Like the latest flat screen with super clear picture quality. It seem that every other week we get the next new and improved product. Just look at washing power or washing up liquid advertisements.

Just some food for thought more to come soon.

PostHeaderIcon Green Tip – Reuse It


Green Tip – Reuse It

It is good practice to reuse as much as you can. It will prevent waste and for plastic items help keep them out of dumps!

Items you can Reuse at least once:

* water bottles. as long as you keep them clean, you can reuse them several times. It will save you money just to refill the bottle with tap. refrigerate it and you are good to go.

* newspaper. you can use old newspapers to clean your windows and mirrors, as shelf liners and more. reusing newspapers can really help save on paper purchases, thus saving trees!

* donate or free-cycle. items like clothes, toys, books…almost anything can be donated or given away instead of tossed. just make sure it is clean and in decent condition.

* make compost. use your unused natural food items to make compost.

* batteries. stop buying one time use batteries and only purchase rechargeable ones.

* refillable. buy condiments, shampoos and the like in large containers and refill smaller user-friendly container for it. This will help you buy less bottles and use less plastic!

* bags. stop using paper and plastic bags. buy canvas bags and reuse them over and over again.

* paper. any time your printer messes up or you make an error when using paper, let your kids use it to color on. or, you can use it as scrap.

* clothing. use old socks, t-shits and cloth materials as rags, to clean the car or to dust with.

* egg cartons. these can be reused for arts and crafts, paint holders, taco items, or even to organize jewelry or small items.

* plastic milk jugs. these can be used for pots for plants or even to water them.

* cardboard boxes. go to a fun place with your kids that has a hill and have a summer sledding competition! cut large squares and use the cardboard as your “sleigh.”

As you can see, there are many many ways that you can reuse items you use everyday. Be creative and brainstorm about how you can make the most of everything and be a good steward to God’s planet!

PostHeaderIcon Reuse and Recycle, THE 3 Rs – Lazy Ways to Reduce


Reuse and Recycle, THE 3 Rs – Lazy Ways to Reduce

The 3 Rs (Reduce, Reuse, and Recycle) is no longer simply a mantra for environmental activists, it’s a ticket to saving you money while you consider the planet. The 3Rs ask you to buy less, reuse more, and recycle products at the end of their useful life-wonderful guiding principles for reducing our environmental footprint and bringing our lifestyles into balance with nature. But in practice, how many of us are really willing to cut back on the stuff we want to own, to reuse what we’d like to throw out, and to recycle when doing so is often incredibly inconvenient? Fortunately for budget-conscious Lazy Environmentalists, the 3Rs are receiving a twenty-first-century facelift, making them easy to implement and even easier on the wallet.

Reduce, the first of the 3Rs, releases you from the hassle, expense, and waste of unwanted stuff while helping you use less energy and create less trash. And while most of us can’t imagine life without our most prized four-wheeled possession, the first place to embrace Reduce is with our cars. That’s because our automobiles generate about half of our personal greenhouse gas emissions-the other half comes from our homes.

Today, you can enjoy the freedom of being in the driver’s seat while eliminating all of the expense of owning-or leasing-and maintaining a car by joining a car-share service. Zipcar is leading the way. Available in more than 40 U.S. cities, Zipcar lets members locate cars conveniently parked at designated spots around the city and reserve them for an hourly fee (typically between $10.50 and $16.50). Members arrive at the parking spot, swipe their membership card over the windshield sensor to unlock the door, hop in, and go. There’s no need to pay for gasoline or insurance; Zipcar has got you covered. You won’t sacrifice your ride either; Zipcar lets you choose from models like the BMW 325, Mini Cooper, Honda Fit, Volkswagen Jetta, Toyota Prius, Honda Civic Hybrid, Volvo S40, Mazda 3, and Subaru Outback. According to the company’s surveys, over time Zipcar members reduce their car usage by as much as 50 percent. Zipcar estimates that each of its cars removes the equivalent of about 15 privately owned vehicles from the road. Other car-sharing services are popping up across the country and around the world. Visit Carsharing.net for a comprehensive list.

Reuse-the middle child of the 3Rs-has been a part of our lives before we were “eco” anything (eco-conscious, eco-savvy, even a tentative eco-curious). Think about it: Every day, we reuse items like T-shirts, cereal bowls, and underwear without a second thought. We don’t toss them after one use. We reuse. The secret to twenty-first century Reusing is to discover how to reuse other people’s really cool stuff as well as our own.

Reuse logic is in effect at Goozex.com, where gamers gather to swap their video game. Visit the website, create an account and list the games you own that you’d like to trade. Then Goozex quickly locates other gamers who want them and makes instantaneous matches for you. With each game you mail, you earn Goozex points, which you can then use to acquire the games you want from other members. Instead of spending lots of money on new games (and paying for all that packaging waste), you’ll pay Goozex $1 each time you receive a game. Whether you’re partial to Xbox, Wii, Nintendo, or many other gaming platforms, the Goozex trading community has got you covered. Get your reused copy of Call of Duty 2 or NCAA Football 09 today.

Swapping websites are emerging in all kinds of categories. Bookworms can browse more than two million titles available for trade at Paperbackswap.com. Movie collectors can visit Swapadvd.com to trade both new and classic DVD titles. CD fans (you know you’ve still got ‘em) can tap into more than 130,000 titles available at Swapacd.com. And new and expecting parents can trade for baby strollers, bibs, bedding, bumpers, and more at Zwaggle.com.

Recycle, the last of the 3R trio, is the most transformative of the Rs. When we recycle, we’re giving used products the chance to be reborn as something new. That’s especially the case thanks to companies like Preserve that has partnered with Stonyfield Farm to recycle its yogurt cups-from organic yogurt, of course-into ergonomic plastic toothbrushes, razors, and an assortment of colorful kitchenware (and now also does the same with Brita pitcher filters).

TerraCycle, another green innovator, is on pace to redefine much of America’s relationship with trash. The company that began with its signature Plant Food-made from worm poop, packaged in empty Pepsi bottles and sold at the likes of Home Depot and Wal-Mart-has evolved into an innovation powerhouse that continually introduces new products made entirely from waste. Take the E-Water Trash Cans and Recycling Bins available at OfficeMax for $10.99 each and made from crushed computers and fax machines (that would otherwise end up in a landfill). Or the rain barrels and composters made from Kendall-Jackson oak wine barrels that sell for $99 each at Sam’s Club. They’re both prime examples of a company that sees opportunity where others see garbage. In so doing, TerraCycle helps us make attractive choices that are mindful of the planet and our wallets.

PostHeaderIcon A Carbon Footprint is Impacted by Fugitive Refrigerant Gas Emissions


A Carbon Footprint is Impacted by Fugitive Refrigerant Gas Emissions

The United States and a host of other foreign countries are focusing on fugitive emission tracking for certain industries. The goal is to identify the amount of substances that are emitted into the atmosphere when a refrigerant gas leak occurs. This will give government officials at the EPA a better understanding of the amount of greenhouse gases harming the environment each year and contributing to global warming due to the ineffective management of refrigerant gases.

Fugitive emission takes place when an unexpected leak of a hazardous substance occurs in a system and the discharge is not contained in a vent, stack, or duct. This may be caused by a component failure, poor servicing, or a breakdown in some industrial process. When a system containing refrigerant leaks, these high global warming potential substances cause damage to the atmosphere. Certain refrigerant gases are not broken down in the atmosphere and end up entering the stratosphere and destroying the protective ozone layer over time.

Across the U.S. economy, refrigerant gases or fugitive emissions equal over 300K tons of carbon dioxide each year. Other countries have similar or worse outputs. Many environmental regulations, such as The Montreal and Kyoto Protocols, exist to reduce the escape of harmful substances, like refrigerants, into the atmosphere over time. There are additional goals to reduce the potential for global warming in the near future and to improve air quality in the long term by reducing the emissions refrigerant gases.

A select few refrigerant gases have multiple detrimental effects on the environment. Not only are they ozone depleting substances but they are also chemicals with a high global warming potential (GWP) which places them into the category of greenhouse gases which lead to global climate change. For many reasons, it is important to effectively monitor, track, and report refrigerant gas usage.

The EPA has finalized its rules pertaining to any fugitive emission occurrence, whether through evaporation or a leak. The regulations apply to several industries, including existing and newly constructed facilities with systems using refrigerant gas in their workplace heating and cooling systems. Other industries are industrial chemical manufacturing, electric services, pulp and paper mills, and petroleum refinancing.

Tracking fugitive refrigerant gases is required by facilities owning or operating HVAC-R systems or by manufacturers who produce them. The EPA has identified a number of dangerous compounds, among them chloroflurocarbons, hydrofluorocarbons, methyl bromide, halons, methyl chloroform, and carbon tetrachloride.

A particular concern for fugitive emission problems is with refrigerant gas, because it contains chloroflurocarbons and hydrofluorocarbons, two primary contributors to the weakening of the ozone layer and the increase in greenhouse gas volumes. Furthermore, refrigerant gas is used across many industries in refrigeration and cooling units, ventilation and air conditioning systems, and fire protection systems.

When a fugitive emission occurs, businesses are required to track the refrigerant leak rates and report annul refrigerant usage it to the EPA. One of the primary emissions scopes, fugitive refrigerant gas emissions are an integral part of an organizations carbon management requirements. Of the utmost importance is the determination of the HVAC-R system that is leaking and the capturing of the service event detail related to fixing the leak. Systems containing refrigerant gases must be inspected by EPA certified technicians and all service events must be logged when refrigerants are handled.

The new fugitive emission regulations provide a more standardized approach to thresholds identified by the U.S. Clean Air Act at the direction of the EPA. These include continuous monitoring, tracking of leaks, and reporting of leak repair, and containment.

Web applications and specialized tools can increase an organization’s efficiencies related to HVAC-R system maintenance, improve accuracy of refrigerant inventories thus saving money, and turn manual processes into a centralized, automated work flow. Development firms who specialize in the area. They ensure compliance and reduce the likelihood of substantial fines.

Water Used in Generating US Electricity

In my four-article series on water use (The Resource Matrix), I took you on a journey to reveal the layers of The Resource Matrix in order to help you understand how water will be a highly contested commodity tomorrow, possibly as much as oil is fought over today.

You learned about your water footprint and a website where you can calculate it, virtual water and virtual water transfers, whereby choices here affect water availability elsewhere, to the point of some people not having enough water to drink in order to produce inexpensive dyed cotton, along with insane choices such as growing crops in the desert.

You learned that on average it takes 1854 to 3000 gallons to produce one pound of beef.

Yep, it’s it’s been a great journey through the sidetrip city of the Resource Matrix.

Today, we’ve found the on-ramp to the Green Lighting Interstate and are driving to take a look at water use in generating electricity.

For a simple reason. It takes a lot of water to produce electricity.

How much? 5% of all US water? 10%? Can’t be as high as 25%?

Electricity and water?

I thought the issue was fossil fuels and greenhouse gases

The U.S. Geological Survey (USGS) estimated water use in the United States in 2000.

Their grand total: 408 billion gallons per day withdrawn for all uses.

The number 1 spot, weighing in at 48%, was thermoelectric power.

Irrigation earned the runner-up prize at 34%.

The 195 billion gallons need to come from somewhere, and actions have consequences. Environmental ones, as in 40 million fish in the Great Lakes killed each year due to being trapped against water intake devices. That’s a lot of Friday night fish dinners.

How much water is used in generating electricity?

Large fossil fuel and nuclear plants require incredible quantities of water for cooling and ongoing maintenance.

Water for thermoelectric power is used in generating electricity with steam-driven turbine generators. It uses 48% of all water in the US.

According to the Pace Energy and Climate Center, the amount of water used for power plant cooling varies by each specific power plant’s electricity generating technology and size. Nuclear reactors require the most water for cooling, and baseload fossil fuel power plants come in second.

The Salem Nuclear Generating Station alone takes 3 billion gallons a day from the Delaware Bay, according to the Pace Energy and Climate Center.

Nationally:

  • Steam electric generating plants across the nation draw in more than 200 billion gallons per day.
  • Nuclear and fossil fuel power plants drink over 185 billion gallons of water per day.
  • Geothermal power plants add another 2 billion or so gallons a day.
  • Most renewable energy technologies require little or no water for cooling.

These numbers are starting to sound like the same ones the U.S. Treasury and Federal Reserve Bank use.

Imagine watching your favorite science program where astronomers explain that the universe is 78 billion light-years wide (78 billion units of 5,878,630,000,000 miles). There is absolutely nothing in our experience to help us wrap our mind around it.

How much is 3 billion gallons per day?

The Delaware Bay feeds Salem Nuclear Generating Station 3 billion gallons a day.

Imagine this rectangle: a football field with end zones (360 feet long x 160 feet wide). Then add to it walls on each side of the rectangle to create a container to hold the 3 billion gallons you pour into it.

How high do you need to make those walls to contain 3 billion gallons? 6915 feet high. Or 1.3 miles.

Maybe 6915 feet high is still hard to imagine. So how deep do you cover the field in order to feed the Salem plant every minute? Answer: 5 feet deep. Every minute.

48% of all water use: We’re Number One!

How much is 195 billion gallons per day?

Using the USGS figure for 2000, thermoelectric power nationwide used 195 billion gallons a day, or 48% of all water used in the US. My guess is the water use has grown since then.

How high are the walls on our football field now? 449,475 feet or 85 miles high. We’re back to US Treasury and astronomy numbers again.

So, let’s get a higher-level view to help us.

Lake Erie holds 116 cubic miles of water.

Nationally, thermoelectric power uses 195 billion gallons a day – or 64.2 cubic miles a year.

We drain Lake Erie every 22 months.

But the water used is returned to its source.

So what’s the issue about water use?

Power generation returns 98% of the water back to its source (bay, lake, river, ocean).

It’s the environmental consequences.

The Pace Energy and Climate Center explains it neatly:

Withdrawal of large volumes of surface water for either power plant cooling or hydropower generation can kill fish, larvae and other organisms trapped against intake structures (impinged), or swept up (entrained) in the flow through the different sections of a power plant.

Examples include:

  • The Salem Nuclear Generating Station is responsible for an annual 11 percent reduction in weakfish and 31 percent reduction in bay anchovy.
  • At the Indian Point 2 and 3 reactors on the Hudson River, the number of fish impinged totaled over 1.5 million fish in 1987.
  • The 90 power plants using once-through-cooling on the Great Lakes kill in excess of 40 million fish per year due to impingement. (Once-through cooling needs a continual flow of new water, and uses 30 to 50 times that of a closed cycle system. Closed cycles cool down water from steam then reuse it.)

The diversion of water out of the river removes water for healthy in-stream ecosystems:

  • Stretches below dams are often completely de-watered.
  • Fluctuations in water flow from peaking operations create a “tidal effect,” disrupting the downstream riparian community that supports its unique ecosystem.
  • A dam’s impoundment slows water flows, which hinders natural downstream migration of many fish species.
  • By slowing river flows, dams also allow silt to collect on river and reservoir bottoms and bury fish spawning habitat. Silt trapped above dams accumulates heavy metals and other pollutants. Disrupting the natural flow of sediments in rivers also leads to erosion of riverbeds downstream of the dam and increases risks of floods.
  • The impoundment of water by hydropower facilities fundamentally reshapes the physical habitat from a riverine to an artificial pond community.
  • This often eliminates native populations of fish and other wildlife.
  • Dams also impede the upstream and downstream movement of fish and other wildlife, and prevent the flow of plants and nutrients. This impact is most significant on migratory fish, which are born in the river and must migrate downstream early in life to the ocean and then migrate upstream again to lay their eggs (or “spawn”).
  • As mentioned above, withdrawal of water into turbines can also impinge or entrain significant numbers of fish.

The cleanest kilowatt is the one never used:

Back to those compact fluorescent lamps and LEDs

PowerScorecard.org explains the solution:

By re-directing electricity dollars to support environmentally benign energy resources, consumers are empowered, in states that offer supply choice, to influence the existing generating resources that are deployed to meet demand.

They can also support the construction of new and cleaner electricity resources that will be built to meet overall growth in demand in the future. By supporting these power options, consumers can minimize many water use and consumption impacts. Still, directing your dollars to cleaner power products in no way helps remediate damages that already have occurred. Consumers can stop the construction of new hydropower facilities or alter conditions of siting and operation, but they cannot undo previous environmental degradation that occurred at existing hydropower facilities.

In short, reduce your use of electricity.

Green Shopping Basics – What You Should Know Before You Shop Green

Going green always starts with good intentions, but the massive amount of green terms can sometimes be overwhelming. Here’s some of the common green terms you’ll hear and what they mean.

Organic
The term organic can often be used very broadly, but typically refers to products that have only organic components, produced without pesticides, herbicides, insecticides, or fertilizers or other harmful chemicals.
Look for: USDA Certified Organic

Sustainable
Products or materials that are described as being sustainable contain materials that do not deplete the Earth of its resources and is easily replenished. There are many common types of materials that are considered sustainable:

Bamboo - Bamboo is a fast-growing and renewable resource that can be used to make fabrics, flooring, furniture and other products.

Jute – Jute is a long and shiny vegetable plant fiber that can be woven into a strong thread or twine. It is commonly used to create cloth or used within carpets, and rugs.

Hemp – Hemp is a fast-growing plant that is most commonly used for its strong fibers to create cloth used in bags and clothing. It can grow organically and also be used to create oils for cosmetic products as well as be used in food.

Sustainable Wool – There are many types of sustainable animal wools such as alpaca fibers or merino wool that can be used to create strong fibers commonly used in clothing.

Energy-Efficient
Products that are energy-efficient are design to consume less energy when operating without sacrificing performance, reducing long-term environmental and cost impacts. Energy-efficient products can range from appliances to light bulbs as well as contain different levels of efficiency.
Look for: Energy Star Qualified, EPEAT Rated

Post-Consumer Recycled
Once a product has completely served its purpose, what remains are post-consumer materials that would otherwise be disposed as waste but are instead recycled. This would include products such as old packaging, glass bottles, aluminum cans, and plastics. When you recycle from your home these products become post-consumer recycled.

How is this different vs recycled? Regular recycled materials can contain a combination of materials, often coming a scraps or other by-products as a result of manufacturing. This could include both pre-consumer and post-consumer waste.

Recyclable
A recyclable product means that it can be recycled and be used to create future products. Polypropylene #5 is a common plastic to look for in products which is one of the most easily recyclable plastics.
Look for: Polypropylene #5

Reusable
Reusable products mean that a product can be used multiple times before the product is discarded or recycled. Some common reusable products are shopping bags, water bottles and tableware.

Fair Trade
Fair Trade is a social movement that promotes certain standards of sustainability practices and empowering producers in developing nations. Fair trade supports fair prices, fair labor conditions, community development and environmental sustainability.

Volatile Organic Compounds (VOCs)
VOCs are organic chemical compounds that have high vapor pressure and easily evaporate at room temperature. VOCs can be released from many household items such as paints, flooring, upholstery, and cleaners. These VOCs are not only air pollutants but have also been known to cause health effects as well.
Look for: Low-VOC, Zero-VOC

Bisphenol A (BPA)
BPA is an organic compound that is used in the creation of many plastics and resins. Most commonly you will find BPA used polycarbonate bottles. While there is some controversy about the effects of BPA, some research has raised serious health concerns about the usage of BPA.
Look for: BPA-free

Biodegradable
Biodegradable means that a substance can be naturally decomposed by biological processes. If a product is biodegradable, this means that it can be disposed of with no negative environmental impacts.

Solar-Powered
Solar powered products are powered using energy from the sun. Solar power can be used in a range of products from small household gadgets to entire home heating systems.

Now you’re ready to start shopping for green products!

PostHeaderIcon What it Really Is: Recycling


What it Really Is: Recycling

Recycling has become the catch all phrase often used in place of the 3 R’s. But in its truest form recycling means taking one thing and changing it, usually chemically, into another. This is not to say that recycling is without value; it is certainly better than putting the items in the bin where they will end up in landfills and leach chemicals into our ground water. It is though to say that before you place anything in the recycle bag, first consider if you could reduce or re-use it, because everything that ends up in the recycling bag will have to be altered before it can be used again. Even then it is cleaner to produce goods from recyclables than from raw materials.

Here are just a few reasons to make certain that after you have reduced the amount of waste your create and re-used as many things as possible that your family puts as many things as possible into the recycling bins:

  • Recycling one aluminium can saves enough energy to run a TV for three hours — or the equivalent of a half a gallon of gasoline.
  • Each ton (2000 pounds) of recycled paper can save 17 trees, 380 gallons of oil, three cubic yards of landfill space, 4000 kilowatts of energy, and 7000 gallons of water. This represents a 64% energy savings, a 58% water savings, and 60 pounds less of air pollution!
  • The 17 trees saved (above) can absorb a total of 250 pounds of carbon dioxide from the air each year. Burning that same ton of paper would create 1500 pounds of carbon dioxide.
  • Recycling plastic saves twice as much energy as burning it in an incinerator.
  • The energy saved from recycling one glass bottle can run a 100-watt light bulb for four hours. It also causes 20% less air pollution and 50% less water pollution than when a new bottle is made from raw materials.
  • A modern glass bottle would take 4000 years or more to decompose — and even longer if it’s in the landfill.

Today is the actually a great day to talk about recycling. Each Thursday the council sends around men to collect our recyclables. The council gives us re-usable sacks, which we can use to collect all paper, cardboard, tin cans, aluminium, glass bottles and jars and plastic bottles. Unfortunately, they do not over recycling for other plastics. As I have been writing this series of blogs that has been one thing that I have been especially mindful of: how much plastic packaging manufacturers use that cannot be recycled and that it is estimated takes over 500 years to decompose in landfills.

But it is not just our plastics, glass, metals and paper that we recycle. Thanks to a wonderful programme through the Islington council, last year we were able to purchase a subsidized wormery to recycle our food waste into compost and liquid fertilizer for growing my own food. Actually, even though we may think that food thrown into the bin will degrade relatively quickly in the landfills, the biggest problem is the amount of methane, a dangerous green house gas, which it produces in that time. Methane is twenty times more potent than carbon dioxide and a major contribute to climate change. While my wormery cannot accommodate meat products I put all peels and unused fruits and vegetables into it. I should soon be harvesting my first patch of compost…just in time for my summer garden.

So how does my family do on recycling? Not too bad honestly. This week we had two bags of recyables and will only have two half full 13 gallon bin bags of other rubbish. Actually hubby and I got into a minor disagreement over the trash last night. One of the first rules of the 3R’s is to only throw out your garbage when the bag is full. In our case though, it had begun to smell. I am still looking for a solution…if anyone has ideas they would be greatly appreciated. But for a family of three adults and one pre-schoolers two large bags of recycling and one full 13 gallon bin bag in a week is pretty good I think. I imagine that there are single people, who put more than one bag in the bin each week.

She was also a single mother for almost five years, before re-marrying the love of her life at the age of forty. Obviously, she has a life-time of training in raising a family on a tight budget. In addition to these real life experiences, she possesses a bachelors degree in health education and a minored in environmental management in her masters programme.

Terri feels strongly that this is one of the most challenging times in history for the family, but she also believes that families with the will and resolve to address the pressing issues of saving money, becoming greener, leading healthier lifestyles and spending more time with one another can endure these challenging times and come out victorious in the end.

Through Frugal Family articles, blogs, videos and social networking, she helps modern families rediscover some lost art forms such as cooking, sewing, and gardening. The goal is not to go back in time or become fanatical, but to help all families find simple and effective ways that fit into their lifestyle to make moderate changes with huge impacts.

Journalism Development

The impression created by the media over years has been held with mixed feelings. Whereas some media corporate world are known to have positively helped transform societies politically, economically, culturally and technologically; some other have only torn the world apart through negative reporting that supports aggressive confrontation, glorifying terror activities to make eye-catching headlines with selfishly money motive.

Similarly, the aggressive, corrupt and oppressive groups and individuals (religiously, politically or economically) have been glorified in the way that sustains situation that steadily extinct some societies.

Their content hardly provided or suggested solutions to alarm-triggering headlines. And much of the media activities have lacked an element of social responsibility that is tangible to give a voice to the voiceless and direct transformative opportunities to the poor, disabled and other disadvantaged groups

Journaling is a key communication tool. All organisms by nature communicate either verbally or non-verbally, yet attempting to make sense of whatever cues that are exchanged or evaluated.

True, we tend to be evaluative of one another whilst trying to figure out what intentions the other party could have towards you. The aim can be to help measure up the relationship that possibly could be developed, whether health or not.

Of course, in certain encounters some people could be threatened, suspicious, lack confidence, defensively withdraw or get on well in a healthy and rewarding relationship. This, indeed, is how communities can influence attitudes and behavior towards one another. That way, we could manage, control and direct directs and behavior. What a powerful tool a pen can be!

But success through journaling it self needs a period of training and practical experience, such that we can communicate to effectively make or unmake relationships or evolve life through the aspects of observing, reading and listening to words and actions of others and things.

The primary motivators to writing is the element of having an opinion yet unique. As part of research steps, one would be required to publish a final report or summarized article from the investigations, results and analyses carried out. Other researchers or students would want to review literature about statements pending investigation. From their successes, investigators either get awards or promotion.

Through practical experience, some people make careers out of their abilities and skills to communicate effectively as writers, as advertising agents, as interpreters and, as counselors or therapists.

Secondary employment too could be provided by journalism like driving, distribution, sale or retailing, legal advising et cetera. Eventually, those associated to it could become social icons or global media giants.

On the other hand, journaling could have important health benefits as stress reliever. By writing about one’s traumatic experience, sufferer could drop so much mental toxins off him or her.

And, at the same time it would help improve on analytical and problem-solving skills crucial in successful dealing with the ever emerging challenges encountered in day-to-day life.

From the natural or ecological sense, journaling or communication significantly help to connect different elements of the eco-system -through the principles of interconnectivity and interdependence.

And through media, we can help improve the dangerous global situations as nuclear conflicts, to make the world a better place for everyone to live in. But this would only be so if we formed a common objective in solidarity to it (non-violence) under the principle of conscious non-violence through tolerance and respect for divergent views.

No Bailouts Necessary – Green Transportation

Unless you have been trapped in a cave for the last seven months you are well aware of the disaster overtaking the American automobile industry. Our government is using billions of taxpayer’s dollars to prop up an industry that has been one of the leading facilitators of numerous ills in our society, which will also take billions of dollars to repair, if it is even possible to do so. 

Air pollution which contributes to increased medical costs, urban sprawl, a negative balance of payments from importing oil and global warming can all be traced at least in part to our addiction to the automobile. Now that I’ve ranted about the autos effect upon our society I also greatly acknowledge that we all, myself included, greatly enjoy the mobility and freedom provided by the pernicious machine. We can’t live with ‘em and we can’t live without ‘em. What are we to do?

A lot has been written about the currently nonexistent plug-in electric car. This machine when it finally hits the market could help solve some of our problems but current pricing estimates place the car in the forty thousand dollar range. I’m sure of one thing, it won’t solve many problems if you don’t sell them and at that price I’d hedge my bets.

However, there is one personal transportation option on the market that fits into all of President Obama’s initiatives for energy self sufficiency, global warming (reduction of green house gases), health care (exercise and weight loss), environmental protection (reduction of air and water pollution), and infrastructure renewal.   That option is the Electric Bicycle.

The electric bike using lithium batteries (traditional lead-acid is very environmentally harmful) can go, depending on load factors and riding habits, roughly twenty miles at twenty miles an hour on one charge. It is almost completely silent, gives off no emissions, does not use foreign oil, does not require much room to operate or park, never needs a tune up and provides exercise. It eliminates many of the drawbacks of riding a traditional bicycle for basic transportation while having few of its own. I recognize that not many of us are hardy enough to ride a bike in the rain, snow or freezing cold but that applies as well to motorcycles, motor scooters and traditional bicycles. The electric bike can get you farther, faster without arriving at your destination soaked in sweat. It can operate in many places where other motorized vehicles cannot and makes taking hills a cinch. Riding five or ten miles to work is no big deal and you can simply pedal around bottled up traffic. Usually the lightweight batteries easily detach from the bike and can be carried into your place of work or school for recharging.

Some electric bicycles offer high tech extras such as LiFePO4 batteries that are good for a thousand recharges, regenerative braking that helps recharge the battery much as a Prius does, and internal gearing to generate more torque for uphill climbs. Most electric bikes use what is referred to as a hub motor. This is not a traditional gear or belt-drive motor but is built directly into the hub of one of the wheels. This motor contains two internal rings of opposing magnets that when power is applied causes the wheel to spin. Such motors need little service and never require oil changes, spark plugs or new belts.

Electric bikes come in several of styles. There are the traditional “beach cruiser” and mountain bike styles as well as electric folding bikes, tricycles and “road bikes”.   The electric folding bikes are particularly interesting. Smaller and lighter than a traditional bicycle, they easily fold up and fit into a car trunk and can be carried on a commuter or subway train with little effort. You can take the train to your stop, unfold the bike and pedal on your way. They are also useful for those who live in tight quarters and have no external place to store their ride.

For those of you that are moderately handy with tools, there are a number of electric bike kits on the market that allow you to adapt an ordinary bicycle into an electric bike. One company, Worldwide Electric Bikes, has a particularly well-designed kit that has many of the features I previously mentioned. These electric bike kits do not require a high level of mechanical ability to install. A few common hand tools, a basic understanding of how things go together and the ability to read directions is all that is required. However, if you don’t know the difference between a crescent and a hex wrench, you may wish to buy a pre-made bike or have someone install the kit for you. If you do choose to go the kit route, you can end up with a much more powerful and sophisticated bike for substantially less money than a factory built electric bike. 

Electric Bicycles in all forms have long been a staple of personal transportation in Europe and Asia where there are hundreds of thousands in operation. In the United States bicycles have traditionally been dominated by the toy or recreation market or for the dedicated enthusiast. In both Europe and Asia, cycling has been a traditional means of basic transportation. I believe that this is going to be more and more the case in this country. People are avidly seeking relief from the high financial and societal cost of automobiles. The electric bicycle, while not a panacea, is definitely poised to help provide a portion of that relief.

Electric Bicycles are inexpensive to purchase, require no license or insurance, have a negligible cost of operation and are totally “green”. So, what’s not to like?

Your Second Hand Clothes: Recycle

Landfill in the UK is becoming a huge problem. With the drop in the price of recycled products, the issue is what to do with all of the waste that we produce. The breakdown of waste in landfill sites creates huge amounts of the greenhouse gas methane. There are also many products that will not breakdown and will remain in the environment for ever with the potential to contaminate water supplies.

Traid, a charity specializing in the recycling of textiles reports that 900,000 tons of shoes and clothing are thrown away each year in the UK. Only 200,000 tons per year are recycled and the rest is dumped in landfill. The government estimates that similar amounts of between 550,000 and 900,000 tons of textiles are thrown away each year.

In addition to the problems of waste and landfill in the UK, there is also the consideration of the energy used and waste generated by the manufacture and distribution of clothing and textiles. Growth of cotton uses a huge amount of chemical pesticides and environmentally damaging cultivation methods. The manufacture of man made fabrics also has a huge environmental impact with. Demand for polyester the most widely used synthetic fabric has almost doubled in the last 15 years. The manufacture of polyester uses large amounts of crude oil and an energy-intensive process. It releases emissions including volatile organic compounds, particulate matter, and acid gases such as hydrogen chloride, all of which can cause health problems for workers by causing or aggravating respiratory disease.

Second hand clothing is becoming more popular as people begin to recognise the real costs of fast fashion. Consumers are becoming more aware of their buying choices and ways that they can help the environment.

Finally, there is one more great reason to recycle second hand clothing. Just because you are fed up with a piece of clothing or it does not fit you nay more, it does not mean that it has no worth. You can make sure that the worth of your second hand clothing is realized by swapping it at a swishing party on a clothes swapping website, selling it or donating it to your favorite charity.

This article was written by Ceri Heathcote for posh-swaps.com, a website for swapping, buying and selling second hand and vintage clothing.

Clothes swapping and buying and selling second hand clothes is a great way to reduce the impact of fashion on the environment and to save money.
