Flame retardants are newest threat for polar bears


Toxins from US, Europe pollute Arctic food chain





By Marla Cone, Los Angeles Times | January 15, 2006, Posted on Boston Globe.



SVALBARD, Norway -- Already imperiled by melting ice and a brew of toxic chemicals, polar bears throughout the Arctic, particularly in remote dens near the North Pole, face an additional threat as flame retardants originating largely in the United States are building up in their bodies, according to an international team of wildlife scientists.



The flame retardants are one of the newest additions to hundreds of industrial compounds and pesticides carried to the Arctic by winds and ocean currents. Accumulating in the fatty tissues of animals, many chemicals grow more concentrated as larger creatures eat smaller ones, turning the Arctic's top predators and native people into some of the most contaminated living organisms on Earth.

This is easier said than done for millions around the world, as evidenced by protests in Mexico over the cost of corn tortillas, and in Italy last September about the price of (wheat) pasta. Staff writer Peter Ford looks at why. Read more....

Climate Confusion: Who Wins?

Image
by Michael O'Brien Climate change is the biggest challenge we face as a humans. Any serious student who analyses the information recognizes that the overwhelming consensus from scientists is that we have a very small period of time in which our efforts will have a positive impact for our planet and our children's future. For the past 10 years or so, there has been rigorous debate both by the scientific community and in the press about climate change. The debate is over, the issues have been discussed and now is the time for us to take responsibility for our future. It is fascinating to watch the media feel the need to present the “other side” of this issue when there is discourse about climate change. My guess is that they feel vulnerable from the vocal skeptics or right wing talk show hosts so they include a dwindling number of scientists or spokespeople who argue against human causation. It seems there is an inordinate amount of air time devoted to this topic in proportion
