2. Definition- A species that is thought to be at risk of extinction in the near future. Scientists have paid more attention to endangered species so they can try to save them from extinction.

3. Habitat loss(deforestation, development, and environmental disasters) Hunting-Either for food or prize. Disease-Which can spread rapidly. Introduction of exotic species that becomes a predator or a competitor. High predator levels and parasitism.

4. Educate others on what is happening and how they can help. Don’t use pesticides or herbicides. Plant vegetables and habitat native to your area. Visit and donate to nature refuges. Create a wetland in your area to provide a habitat for many endangered species. Buy eco-friendly products Report poachers to local law enforcement.
