You are wrong. Google polar bear hunting history facts. The primary pressure on the bears until 1973 was hunting with hundreds taken annually just in Svalbard.
In canada, the hunting was never real high. They just thrive.
There is a tremendous amount of ignorance about polar bears. There has never been a good survey of the population.
Measurements are not available to large areas of their range.
Several hundred to over a thousand were harvested (estimated for Russia) for over a hundred years. 450 a year in the Russian area, which included Svalbard, were harvested from 1700 to 1875, according to one Russian researcher, Upenski.
You cannot harvest that many over that long unless the population can easily produce that many.
We really do not know how many polar bears there are, or what the carrying capacity is of their range.
The amount which can be harvested is certainly over 500 a year and is probably over 3000 a year, which would be about 15% of the lower estimates of their current population.
There could be 50,000 polar bears on the planet... We simply do not know. Researchers don’t like to release population data, probably because their population forecasts, based on false assumptions about climate change, have been so wildly wrong.
