Toxins in common products

You have probably heard of Brominated Flame Retardants that are found in many mattresses and carpets. Although BFRs are used to reduce the risk of fire, they are a group of manufactured chemicals that can cause disrupt thyroid stability and normal hormonal balance and also affect the immune system.

But there are toxins in other common products that you may not be aware of… Some of these toxins occur during production, use, or disposal of the product. For example, cadmium can be released during cigarette smoking, but not during the production or disposal of the cigarette. Arsenic in pressure-treated wood (pre-2004) can be released during any part of the product’’s life cycle.

Monumental: David Brower’’s Fight… (2005)

Monumental: David Brower’’s Fight for Wild America, is the story of the greatest conservationist since John Muir. The film begins with David Brower in his early days, with a small local group of mountaineers called ”The Sierra Club,” who enjoyed hiking and rock climbing in Yosemite and other areas. As time passes, Brower becomes more concerned about the protection of the earth’’s wild places.

He also becomes friends with the great photographer, Ansel Adams, and through Adams” work, he learns the importance of using images in the cause for environmental preservation. This becomes evident throughout the film, as you will see lots of short segments taken from films that Brower put together to draw public awareness to specific issues.

Brower’’s proficiency as a climber also continues to evolve, to such an extent that after he climbs Shiprock in the late 30s, he begins training US mountain ski troops at the 10th Mountain Division Training Camp. He and his battalion are then sent to Italy to fight in WWII.

When he returns from the war, the economic boom in the U.S. contributes to large scale development that begins threatening the wilderness areas. More tourists head to the parks and wilderness, wanting changes made for convenience and recreation. New demands on resources begin making it popular for politicians to want to put dams in the parks. Brower becomes an strong advocate in protecting the parks and he is hired as executive director of the National Sierra Club in 1952.

One of the battles that would have a profound effect on Brower was the fight to protect Dinosaur National Monument. As part of the Colorado River Storage Project, there was an attempt made to place dams at Dinosaur National Monument. The region was largely unknown to the general public. He started doing river trips to draw attention so that people would take the trips, gain an appreciation of the region, and return home to write to their Congressional representatives. At that time, he also put together a film called ”Two Yosemites” to draw a connection between Dinosaur National Monument and what had happened in the Hetch Hetchy/Yosemite.

Despite Sierra Club efforts, a Congressional Committee approved the dams. However, Brower was then able to prove deception which resulted in Congress dropping the dam projects in 1956. On the same day, a key proponents of the dams, Interior Secretary Douglas McKay resigned. For the first time in U.S. history, conservationists were able to halt a major governmental development project. As a concession, the Sierra Club agreed not to oppose dam sites outside of national parks, resulting in the destruction of Glen Canyon. This would become a deep regret for Brower who said he had been willing to sacrifice Glen Canyon in order to save Dinosaur Canyon, “simply because I didn”t know what was in Glenn Canyon and that was one of the bitterest lesson I ever had.”

After this experience, Brower took a bolder stance on conservation issues with the view that compromise leads to regret. In 1960, Brower and the Sierra Club set 5 goals–all of which are accomplished by the end of the decade. Among these successes, which the film covers in some detail: the establishing of Redwood National Park, the passing of the Wilderness bill, the establishing of North Cascades National Park, the stopping of 2 dams in the Grand Canyon, and the establishing of Point Reyes National Seashore. In addition, Cape Cod National Seashore was also established. These were very ambitious goals considering that in 1960, most of the American public viewed Earth as little more than a resource, and the film is good at illustrating how these efforts were not only resulting in action, but they were also having an effect on the way people were beginning to look at their environment. There was a growing realization that the Earth’’s resources were not limitless.

In the late 1960s, Pacific Gas & Electric (PG&E) wanted to put a nuclear plant on the south coast of California at Nipono Dunes. In an effort to save Nipono Dunes, the Sierra Club made a deal with PG&E that it would not oppose construction of a nuclear plant at Diablo Canyon. However, Brower refused to accept the compromise, and consequently, he was fired as organization’’s Executive Director. He then started Friends of the Earth which became very active in the fight against arctic drilling. After 13 years of service, Brower was fired from Friends of the Earth–once again on issues of compromise.

David Brower

In 1980, he founded the Earth Island Institute, and in 1983, the Sierra Club elected Brower to board of directors. He served with the Earth Island Institute and the Sierra Club until he died in 2000.

This film is full of still photos and wilderness film footage shot between 1930-1970. Despite the age of some of the film, there are quite a few scenes that are simply striking.

Overall, this is very a moving film about a remarkable man who was a great champion for our earth and its wild spaces.

How Cuba Survived Peak Oil (2006)

[Editor note: Just caught this film at the Dallas Video Festival last weekend.]

When the Soviet Union collapsed in 1990, Cuba became the first country faced with the peak oil crisis. Suddenly a supply of 13 million tons of oil a year dropped to 1 million. The change was seen almost immediately - within weeks. There were power outages, no air conditioning, and no elevators running. People tried to get to work with whatever transportation was available only to discover that there was no electricity at their jobs. The Cuban government had to import 2 million bicycles for transportation. Even construction was severely limited because cement production requires high levels of fuel.

However, the biggest and most immediate problem became food scarcity. There was no fuel to transfer food and no electricity to refrigerate it, and the massive use of oil-based fossil fuel for pesticides and farm machinery had disappeared. Within the first few years of this crisis, these constraints, coupled with the continued U.S. blockade on food, resulted in an average weight loss of 20 lbs for most Cubans.

With hunger spreading, people were left with no other choice and resorted to growing food wherever they could, and this led to widespread urban gardening.  Famine was prevented by converting every open space in the city into gardening. Because they could no longer get access to oil-based pesticides, farmers had to resort to growing food organically. This was not easy. After years of large commercial farming with pesticides, the land didn”t respond right away to organic measures. It would take 3-5 years to make the land fertile and productive again with organic methods. Today 86% of Cuba’’s agricultural production is organic.

Farmers also began the practice of crop-mixing to reduce pests, and scientists began making and exporting bio-pesticides. Changes also resulted in smaller farms and more privately-owned cooperatives. Decision making became localized with fewer state regulations. Even schools became more decentralized.

Private farmers began having the highest levels of production. A sense of ownership led to greater productivity as more people began moving to rural areas to start private farms. Also, sugar mills began being converted into power plants.

Despite the many problems that Cuba continues to face, the Cubans have managed to find a way to use less energy. Today, the average Cuban uses 1/8 the energy of the average American. They also eat more vegetables, bicycle everywhere, and place a greater value on science and health care. (Although Cuba represents only 2% of the population of Latin America, it has 11 percent of all the scientists.)

Whether you view peak oil as real and inevitable, or as just a `market creation,” I think that you will still find this film interesting and insightful-and perhaps, inspiring.

Too Hot Not to Handle (2006)

Too Hot Not to Handle covers similar ground as An Inconvenient Truth, except that it is more visually interesting and Al Gore is not providing the narration. In other words, if you have some friends who are politically conservative and lack the attention span to sit through a detailed lecture, this might be the DVD to send them.

The film explores the effects of climate change in the U.S. and it looks at the human activity that is making the earth warmer than it has been in millions of years. It points out that almost all of our use of energy is leading us down this path. too hot not to handle

There are many activities already occurring such as extreme weather, changes in migration patterns, disappearing snowpacks, increases in forest fires, and increased droughts. in some wet places, it is getting wetter. Since 1970, the average number of class 4 and 5 hurricanes per year has doubled.

Future activities are also examined. For example, if current trends persist, there is the possibility of having millions of ”climate refugees.” As warm areas become warmer, many mosquito borne viruses will begin to move north. West Nile virus will not grown in a mosquito above 60F. In 2004, West Nile was found in Lake Tahoe. Also, freed C02 seems to benefit many weeds. Ragweed grows bigger and produces more pollen, and so there is the potential for a hyper production of pollen. An increase in C02 will also increase the resistace of ragweed to herbicides.

There is the tendency by some people, when faced with the shear enormity of climate change, to try to discount it as ”doom and gloom” or political posturing. However, as this film shows: there is just too much evidence. And it’’s to the credit of this film, that the evidence is presented throughout the film by actual high-level scientists who are experts in climate and geology. They are not: 1) actors turned opinion-makers, 2) enterprise institute hacks turned ”pop” climate experts, or 3) doctors turned fiction authors.

In response to criticism that the temperature will change only by a small number of degrees, one commenter, Richard Somerville responds: “You can die of symptoms from a fever that is only a few degrees above normal.”

too hot not to handle

And finally, there is the enormous impact on living things and serious concerns that 1/4 of all plant and animal species could be extinct by the end of this century.

The overwhelming message is that something has to change. Bigger, bigger, and bigger is not going to help. The world we live in tomorrow is going to be different than the one we”re living in today, and it will require changes.

Get states” energy profiles, statistics, and comparisons

At the DOE’’s State Energy Profiles website, you can get lots of information on a state’’s energy production and consumption, and compare energy information by state.

For example, this location provides a profile on Texas, where you”ll find out that Texas produces and consumes more electricity than any other state. Other types of information given is shown below.

  • Prices paid for electricity, coal, natural gas, and how those prices compares with other states.
  • Example: In February 2007, the domestic crude oil first purchase was $55.12/barrel compared to the national average of $52.93/barrel

  • Major coal mines, petroleum refineries, non-nuclear eletrcity generation plants, and nuclear power plants–and who owns them and where they”re located.
  • Example for Coal: Jewett Mine/Texas Westmoreland Coal Co., Oak Hill Strip/TXU Mining Co. LP, Beckville Strip/TXU Mining Co. LP, South Hallsville No. 1/Sabine Mining Co., Big Brown Strip/TXU Mining Company LP

  • Consumption statistics for specific types of energy
  • Example: As of 2000, TX usage of electricity for home heating was 30.3% of the U.S. average.

  • The number of alternative-fuel vehicles in use
  • Example: As of 2003, there were 55,820 alternative-fuel vehicles in use, and as of 2007, there were zero ethanol plants.

  • The percentages of electric power industry emissions for carbon dioxide, sulfur dioxide, and nitrogen oxide
  • Example: As of 2005, the electric power industry in TX emitted 10.3% of all U.S. carbon dioxide (approximately 258,660,697 metrix tons.

Kilowatt Ours (2004)

Kilowatt Ours addresses the relationship between electricity use and the environment, focusing specifically on the southeast U.S. where Amercians use the most electricity and problems are most severe. The film begins with the destruction of mountains in West Virginia, which are actually being blown apart to get at their coal.

west virginia mountains coal

Over half the electricity consumed comes from coal and a typical home in the southeast burns six tons of coal.

1 kilowatt hour = 1 pound of coal = 10 lights bulbs per hour

Vice President Dick Cheney tells Congress, ”With current electric trends, we”ll need one new power plant every week for the next 20 years.” But the film moves on to point how how ”adding just another power plant” is not only backward but can have devastating consequences.

One of the more shocking images in this film is the explosion and destruction of the Appalachian mountains. One resident looking from his backyard said, ”People ask me why I didn”t take a picture. Well, you just don”t expect a mountain to disappear.”

The less visible effects of coal is what you can”t see in the air. When coal is burned, the mercury, which is very volatile, escapes into the air. Mercury is highly poisonous and it’’s a developmental neurotoxin. When a woman is pregnant, the fetus is very susceptible, and there is a great risk that the baby could be born with neurological defects that it never recovers from…effects that can later result in poor behavior in school, learning difficulties, difficulties to find a job, future low earnings, etc.

In addition to causes poisoning in fetuses, the pollution from coal power plants also creates asthma and impairs lung development in children. Children who grow up in clean air have 10% better lung development. When you look at all these factors, can we really afford this kind of coal burning?

coal asthma children

In the same region are the Smoky Mountains, and most of their smokiness these days comes from a haze of sulphate particulates originating from power plants.

The ultimate message of Kilowatt Ours is this: Every time we turn on a light or use electricity, we contribute to these problems. Throughout the film, Barrie and his wife, Heather, show how they take steps in their home to reduce carbon and on a limited budget. And the film’’s latter half focuses on what individuals and businesses can do to reduce consumption.

One step is to switch to compact fluorescent bulbs, since lights devour 40% of electricity.

cf lights coal

Given that schools spend more on energy bills than on PCs and textbooks, Smith Middle School at Chapel Hill, NC switched to ”daylighting” (using skylights and other natural lights to replace a lot of electric lights). They say they saw an improvement in student performance, test scores, and behavior. Sumner County Schools had a 260,000 sq ft school using geothermal which will save $5000 per month. Thousands can be saved just by turning off computers before weekends and holidays.

The film also highlights examples of specific cities” efforts to conserve and save money. For example, Birmingham changed its traffic signals to LEDs and saved $220,000.
