Causes

Habitat Loss
 * 1. Human Impact**
 * __Pollution__: Humans are the main cause of pollution. The environment of the species was polluted with the air produced by the industry; factories.
 * __Destruction__: Destruction such clearing forests or burning forests was made to:
 * provide lands for livestock

The species are all linked together by a food chain in an ecosystem
 * 2. Ecosystem Disruption**
 * Once it is broken, a species becomes extinct, then the food chain will collapse
 * The extinction of one species leads to the extinction of many other species

 * 3. Climate Change**
 * "Climate change may drive a quarter of land animals and plants extinct"
 * Humans use of greenhouse gas caused global warming, which affected many arctic animals such as the polar bears
