All these "what ifs", and "maybes" accepted as the truth is laughable. This is what I call "bogus science", when any abnormality is contributed to the political objective of the "watermelons". In case you don't know, watermelon describes the new environmentalism, "green" on the outside, "red" on the inside. Old commies in new clothing! "Capitalism is the enemy, it's big business that is at fault!" (Pollution is caused by successful industrialized nations!) You may now criticize my poiint now.
Polar bears, Arctic foxes and Inuit peoples are under threat from man-made toxins such as polychlorinated byphenyls (PCBs) that build up in the food chain, new research reveals.
Environmental and animal groups are calling for a global ban on the production of the chemicals to SAFEGUARD the future health of those groups. Some scientists BELIEVE the PCBs are leading to "gender-bender" polar bears in Norway and Greenland, after the discovery of a number of female bears which had both male and female sexual organs.
The report, produced by the Arctic Monitoring and Assessment Programme based in Norway, said the toxins followed air and water currents from as far as Asia to the remote and fragile Arctic environments of North America, Greenland and the Svalbard islands north of Norway.
"Inuit in Greenland and Canada have among the world's highest exposures to certain toxic chemicals as a result of long-range transport," said the report, Arctic Pollution 2002.
The toxins, including POTENTIALLY cancer-causing PCBs, build up in the food chain, especially in fatty tissue such as blubber in whales and seals. Blubber, being high in energy, is a key part of the diet for polar bears and the indigenous people of the Arctic.
Samantha Smith, the director of the International Arctic Program for the World Wildlife Fund, which has endorsed the study, said: "Those at the top of the food chain are hit hardest, and those are polar bears and humans.
"Most of these chemicals come from outside the Arctic, including the southern hemisphere, and are carried by wind and water currents.
Without a global ban, we can't protect indigenous peoples and wildlife in the Arctic."
In a separate study, female polar bears with both male and female sexual organs were discovered in 1997 on Norway's Svalbard archipelago, about 300 miles (500km) north of the Norwegian mainland. Researchers at the Norwegian Polar Institute now BELIEVE the deformity MAY be due to PCBs and other toxins.
Ms Smith said similar hermaphrodite bears had also been found on Greenland. Such instances have previously been PUT DOWN to the effects of accumulated PCBs. Though they are not believed to have the same effect in humans, they are THOUGHT to be carcinogenic.
Arctic foxes, seals, killer whales, harbour porpoises and birds also suffer high levels of contamination by persistent organic pollutants that damage the nervous system, development and reproduction.
PCBs are chemical compounds that do not occur naturally; they were once widely used in plastics and electrical insulation and can be produced by incomplete combustion of plastics. It can take decades for them to break down. Their use is now largely banned in the West.
The Arctic Monitoring Programme also said levels of organic mercury, which can harm health and even cause death, had risen alarmingly, partly due to increased burning of coal in South-east Asia.
The Inuit Circumpolar Conference, which represents Inuit peoples in Alaska, Canada, Greenland and Russia, expressed concern at the report's findings and called on Arctic governments to work together to help protect the health of indigenous people.
In May, the WWF warned that polar bears COULD disappear from the wild within 60 years due to global warming, which it said was already causing numbers to dwindle. The pack ice, which the bears need to travel long distances for food, has been thinning as temperatures rise, LEADING TO FEARS that it will eventually be too thin to let them travel. When that happens, the population of about 22,000 COULD die out.
The sky is falling! The sky is falling, Comrade!Boogaboogaboogabooga!
