The document discusses several endangered animal species and the environmental threats they face:
- Polar bears live in the Antarctic peninsula and are threatened by hunting and climate change reducing their sea ice habitat.
- Only 100 Siberian tigers remain due to hunting of the beautiful cats for their skins.
- The population of Humboldt penguins in Chile has declined to just over 12,000 due to overfishing reducing their food supply.
