Your view but on what basis? A cursory search seems to me to show that thanks to the difficulty of gathering evidence, anyone can find data supporting an increase or a decrease in their population.
- CalRobert 10y agoGenerally speaking large changes to a creature's habitat are challenging. The arctic is undergoing massive changes, including rising temperatures and a reduction in sea ice, necessitating longer swims, increasing energy expenditure without, it seems, an increase in the seals and the like which polar bears eat. Also, the frequency of twins appears to have dropped (though, again, this data is not easy to gather), and that seems to be a response to stresses.
