The man-made global warming scam alarmists really like to use the cute polar bear to tug at the heart strings of those who don't know any better. They just want you to submit to carbon taxes.
The bears are not becoming extinct. The climate has always changed naturally, and animal populations will reflect these change in habitat.
There is a poster on CP here (forgot his name) who lives in the arctic that said himself that the polar bear die off is hype not supported by reality.
Here is a fair article talking about polar bears.

Most polar bear alarmism by the way, was again established from "projections" into the future by climate alarmists. I think they claimed that the population was going to be reduced by 2/3 in 50 years or something to that effect..........hogwash.
