Clean drinking water...not self-evident for ev...

Is your drinking water safe? -Wikipedia

The U.S. Environmental Protection Agency (EPA) is ordering a natural gas company in Fort Worth to take immediate action to protect people living near one of its drilling operations who have complained about flammable drinking water coming out of their home faucets.

Read some of our earlier blogs about the process that is suspected of causing these kinds of  problems:

Read other recent posts about our regulatory agencies’ failure to adequately insure the safety of Texan’s drinking water:

Natural gas drilling (or fracking) near homes in Parker County west of Fort Worth has caused or contributed to the contamination of at least two residential drinking water wells, and the EPA  has confirmed that extremely high levels of methane in local water supplies pose an “imminent and substantial risk of explosion or fire.” The agency also found other contaminants including benzene, which can cause cancer, in the drinking water.

The EPA has issued an imminent and substantial endangerment order under Section 1431 of the Safe Drinking Water Act and has ordered the company to step in immediately to stop the contamination, provide drinking water and provide methane gas monitors to the homeowners.  EPA has given the company 24 hours to assure them that it will comply with the order and 48 hours to provide alternative water supplies to affected residents.

Last weekend professors and scientists from four major Texas universities joined forces to write an editorial in the Houston Chronicle defending the science of global warming from skeptics and deniers.  Check it out!

On global warming, the science is solid

In recent months, e-mails stolen from the University of East Anglia’s Climatic Research Unit in the United Kingdom and errors in one of the Intergovernmental Panel on Climate Change’s reports have caused a flurry of questions about the validity of climate change science.

These issues have led several states, including Texas, to challenge the Environmental Protection Agency’s finding that heat-trapping gases like carbon dioxide (also known as greenhouse gases) are a threat to human health.

However, Texas’ challenge to the EPA’s endangerment finding on carbon dioxide contains very little science. Texas Attorney General Greg Abbott admitted that the state did not consult any climate scientists, including the many here in the state, before putting together the challenge to the EPA. Instead, the footnotes in the document reveal that the state relied mainly on British newspaper articles to make its case.

Contrary to what one might read in newspapers, the science of climate change is strong. Our own work and the immense body of independent research conducted around the world leaves no doubt regarding the following key points: (more…)

Sixty seconds doesn’t seem like a lot of time; however, there are lots of things that can be done in sixty seconds or less.  For instance, an average adult can type 38 to 40 words and blink between ten and 30 times every sixty seconds (sometimes simultaneously).  Furthermore, an elite distance runner can run about 180 steps every sixty seconds and the world’s fastest rappers can recite over 723 syllables in even less time.

There are a lot of things an average person can do in sixty seconds or less in their everyday life that will, more or less, benefit the earth.  So here it goes…

  • Switch out your light bulbs to ones that are more energy efficient.

Remember that every time you turn on a light in your home or office you send a message to the power grid, demanding more energy.  In America, 301 million people share the same power grid.  That’s five percent of the world’s population, inevitably sucking up a quarter of the earth’s energy. Over half of the grid is powered by coal plants alone, which are the nation’s number one culprit for greenhouse gas emissions and other pollutants.  The Environmental Protection Agency (EPA) estimates that, for every kilowatt hour of electricity generated by a coal-fired plant, 1.43 lbs of greenhouse gases are released into the atmosphere.  In Texas, 144 lung cancer deaths and 1,791 heart attacks a year are attributed to pollution from power plants. Switch to energy efficient light bulbs and cut the amount of energy you use by two-thirds.

  • Conserve water by turning off your faucet when brushing your teeth or taking less time in the shower.

The average American family consumes around 300 gallons of water everyday. This works out to be 495,000 gallons per person every year.  What boggles my mind is the fact that there are about 1.2 billion people in the world who don’t have access to clean, portable water and here we are overestimating the frugality of our supply.  We have to realize that water is fast becoming the world’s ultimate commodity, and water conservation is the most cost-effective way to reduce our demand for it.

There are several quick and easy things you can do in your home or change in your daily routine to conserve water.  First, you can simply cut your shower time by 60 seconds or more.  If every member in your family does the same, you can end up saving 200 to 300 gallons a month.  Also, if you are a fan of hot showers and hate the first 60 seconds or so of cold water that first escapes the showerhead, you can use a container to catch the cold water and save it for when you want to water plants or rinse your vegetables.  Second, turn off your faucet when you are brushing your teeth or shaving, and don’t leave the water running when you’re washing dishes—fill one of your sinks for rinse water instead.  These simple acts can save three gallons of water in one day alone.

  • Read your product labels.

The production and distribution of all kinds of clothing have a tremendous impact on the environment.   Wool comes courtesy of sheep, whose herds are known to burp and err… otherwise emit methane—a greenhouse gas that is almost 20 times more powerful than carbon dioxide. In countries like New Zealand, methane is fast becoming the most potent greenhouse gas.  Researchers for the United Nations now believe that livestock industries are a major contributor to climate change—being responsible for more greenhouse gas emissions than cars are.  Furthermore, the method of growing cotton is extremely petrochemical-intensive.   About ten percent of all agricultural chemicals in the United States are used to produce cotton, which is grown on just one percent of all major agricultural land.  The process of growing cotton requires 110 pounds of nitrogen fertilizer per acre.  At the end of the day, the use of these synthetic fertilizers and soil additives can wreak havoc on our soil, water, and air supply–leading to oxygen-less deadzones or even acid rain.  Some popular fashion outlets like H&M are now carrying lines of eco-friendly garments, including those made from organic cotton.  Green is the new black; be aware of where your clothes come from and how they are made.

As for the ever popular subject of organic food…

One may enjoy biting into the more conventional, juicy fuji apple—truly nature’s candy, and some say the sweetest apple in town; however, the organic gala apple is just as good as the former, but better for you and for the environment.  It’s true that organic food products are almost always more expensive than the more conventional fruits and vegetables; although, it would only be fair to point out that organic farming is a major player in the effort to combat global warming.  Birthed during the organic movement of the 1930s and 1940s, today organic farms cover a mere 0.8% of the total farming area in the world. Many people don’t realize the great benefits organic farming offers to our land, lives, and livelihood.  Aside from its major contribution of reducing carbon dioxide emissions (done by sequestering carbon in the soil), organic farming also (1) cuts production cost by 25% to 30% for farmers, (2) reduces soil erosion by up to 50%, (3) has a positive effect on the ecosystem and groundwater supplies, and (4) preserves the original nutritional content of food, giving consumers a healthier and fresher substitute.

  • Reuse and Recycle: refill your water bottles and separate your trash.

Ever buy a bottle of water before working out at the gym, or have a bottle of water with your lunch?  Have you ever contemplated the existence of that bottle of water and how it can affect the environment, even after you have used it?

The United States is the largest consumer of bottled water in the world, with Americans chugging a little less than seven billion gallons in 2004 alone.  It takes one and a half million barrels of oil a year to produce the part polyethylene terephthalate plastic bottles made in the U.S.  That’s enough oil to fuel 100,000 cars commuting into downtown Austin daily (this is also another issue that needs to be tackled).  Globally, it takes more than two and a half million tons of plastic per year to make water bottles.  This is a process that requires a whole lot of energy and, in the end, leaves us with heaps of unwanted plastic waste worldwide. Now, I’m not saying to boycott bottled water.   I am just saying that if you do purchase bottled water—and do so frequently, don’t throw the bottle out right away.  You can reuse the bottle—refilling it with water from the tap or water fountains.

Furthermore, by taking 60 seconds to put your newspaper, tuna can, or salsa jar into a separate recycling bin you can ultimately save humanity years in environmental damage.  About 60% of the household trash thrown away everyday can potentially be recycled.

  • Say something!

Probably one of the simplest things an individual can do to bring awareness to green issues and hopefully effect change is to speak up and say something.  You can talk to the manager of your local supermarket and ask that they carry more organic products.  You could call or email your local representative to speak about environmental issues that affect your family, neighborhood, city, or state.

60secondsWhy not take 60 seconds out of your day to save the earth?

Yours truly,

Did you know that in the United States, the average person throws away around 100 pounds of food scraps per year? According to the USDA, “just over a quarter of the country’s food — about 25.9 million tons — gets thrown in the garbage can every year.”

But food is biodegradable, and decomposes in the same manner no matter where we throw it out, right? Wrong. While we should all try to throw away less food, composting what we do toss-out reduces the impact on the environment.

Any food scraps or leftovers that the dog doesn’t eat decompose in one of two ways. Due to the airtight nature of landfills, the food we throw away with the rest of our trash decomposes in an anaerobic manner (without oxygen). One of the bi-products from anaerobic decomposition is methane, which is a stronger greenhouse gas than carbon dioxide. In the first 120 days in a landfill, every metric ton of food can generate .25 metric tons of methane. On the other hand, food that decomposes aerobically (with oxygen) in a compost pile generates carbon dioxide – which is 25 times less potent than methane. If the U.S. composted the 25.9 million tons of food we throw out each year, the effect would be as if we removed 7.8 million cars from the road!

Because oxygen is the golden ingredient, it is important to allow air to get to your compost through the use of a functionally designed container, through turning your compost, or by using worms as a way to ensure oxygen can do its job. Read more about the basics of composting here.

According to the Composting Council the largest benefit from composting is avoiding the production of methane. But, the benefits don’t stop there. When compost is used in agricultural practices :
• Irrigation needs decreases by 30-70%, due to improved water retention in soil;
• Fertilizer (expensive, and often harmful to the environment) needs decrease by 33-66%;
• Carbon sequestration of soil increases by 6-40 tons of carbon per hectare.

Okay, so for those of you who live in farmhouses – or at least have a backyard and a small garden – composting seems like an easy and beneficial practice. You barely have an excuse! But, this is more of a challenge for the 80% of us in the US who live in urban areas. Where do we put a compost pile, and what do we do with it? Thankfully, there are a few options.

First, you can do as my cousin Elizabeth does in New York City. She freezes her food waste, and brings it to the Union Square Greenmarket once a week, where a farmer she knows gladly accepts it for the wholesome treasure that it is. Next time you are shopping at your local farmers market – ask around! Similarly, you can find a composter that accepts food waste in your area, where you can drop off your compost.

A second option, especially if you have a bit more room, or any indoor or outdoor plants that will benefit from it, is to start a worm bin. Worms love to eat kitchen scraps, and the nutrient-rich castings they produce are great for soil. There are many resources on vermicomposting – a great one is cityfarmer.org, published by Canada’s office of urban agriculture.

The third way of urban composting, and possibly the most important way towards the institutionalization of urban composting, is to tell your city officials that you live in an apartment, that you want to compost, and that you think it is high time for them to implement a curbside composting program. If you don’t think your city is “green” enough to do such a thing, look for inspiration and practical advice from San Francisco – where starting October 21 , it will be illegal not to compost, or other cities including Seattle, Boulder, and Minneapolis-St Paul.

Finally, if composting at home just isn’t going to happen for you, (at least until your city starts providing curb-side composting), talk your employer into it. For instance, the National Press Club has just started to compost, and plans on preventing 2 tons of food per month from heading to the landfill. Some state facilities such as prisons and universities also compost – for example, the state prison facilities in Nashville composts leftovers, and uses the compost on its own 100-acre vegetable garden, and Iowa State University has a compost system that can handle more than 10,000 tons of waste per year.

As an introduction to next week’s Green-up your life! blog – getting children involved – talk to elementary and high school administrators about starting a community compost project. By throwing away less food, composting the food we do throw away, educating our community members, and getting state institutions involved, we will soon be en route to a true environmental revolution!
