1. World population growth 1700–2100, 2022 projection. Population projections are attempts to show how the human population statistics might change in the future. [1] These projections are an important input to forecasts of the population's impact on this planet and humanity's future well-being. [2]
Currently, there are only 31 (95% CI: 32-38) bears left in the Mongolian Gobi Desert; through long-term genetic monitoring it is known that the population is relatively stable, however, the sex ratio is highly skewed towards males. [4] Gobi bears are separated by enough distance from other brown bear populations to achieve reproductive isolation.

[85] The bears also isolate walruses when they overwinter and are unable to escape a charging bear due to inaccessible diving holes in the ice. [86]
As a result, the diet is less nutritional, which leads to reduced body size and reproduction, thus indicating population decline in polar bears. [91] The Arctic refuge is where polar bears main habitat is to den and the melting arctic sea ice is causing a loss of species. There are only about 900 bears in the Arctic refuge national conservation ...
According to a 2018 study by Netherlands ecology professor Jeffrey Harvey and others, while Crockford has neither conducted any original research nor published any articles in the peer-reviewed literature on the effects of sea ice on the population dynamics of polar bears, her blog, Polar Bear Science, was a primary source used by websites that ...

Inuka was born in the Singapore Zoo in 1990, the result of an extensive breeding programme run by the zoo and was the first and only polar bear to be born in the tropics.
