Polar bears are endangered due to global warming and pollution. There are approximately 20,000 polar bears left who live in the Arctic. Asian elephants are also endangered with only around 50,000 remaining. They live in forests which are threatened by loss of habitat from deforestation and hunting/poaching. Global warming and pollution endanger polar bears and giant pandas while loss of habitat, hunting/poaching, and global warming threaten tigers, rhinos, snow leopards and Asian elephants.
