Q: Why all the fuss about polar bears? Aren't their populations increasing: in fact, booming?
A: One of the most frequent myths we hear about polar bears is that their numbers are increasing and have, in fact, more than doubled over the past thirty years. Tales about how many polar bears there used to be (with claims as low as 5,000 in the 1960s) are undocumented, but cited over and over again. Yet no one I know can come up with a legitimate source for these numbers.
One Russian extrapolation presented in 1956 suggested a number of 5,000 to 8,000, but that figure was never accepted by scientists. The fact is that in the 1960s we had no idea how many polar bears there were. Even now, about half of our population estimates are only educated guesses. Back then, the best we had over most of the polar bear's range were uneducated guesses.
