More on polar bears

Here.

Excerpt:
Polar bear populations has increased dramatically from the 1960s to our time from about 5,000 individuals to about 25,000 individuals. It appears to be stable.

It is correct, as they point out, that the [Western Hudson Bay] population is down from 1,200 individuals in 1987 to about 950 individuals in 2004. What they omit is that the same population increased from 500 individuals in 1981. That gives a different picture, which does not indicate a species on the brink of extinction.

Another piece of information that changes the statistic is that 49 polar bears are shot annually in the Western part of Hudson Bay. 833 polar bears have been shot over 17 years from 1987 to 2004. That is far more than the ones assumed to have lost their lives due to global warming.
