What are the 6 main reasons most species become endangered?
Loss of habitat, the introduction of a foreign species into the environment, hunting, pollution, disease, and loss of genetic variation are all causes of species decline and most often are a result of human activities.
What is the main reason why species become endangered today?
One of the most significant causes of endangered animals is habitat loss. While habitat may be lost due to natural forces (climate shifts, geologic changes), much of the habitat lost today is due to human activity.

What are the effects of endangered species?
Healthy ecosystems depend on plant and animal species as their foundations. When a species becomes endangered, it is a sign that the ecosystem is slowly falling apart. Each species that is lost triggers the loss of other species within its ecosystem. Humans depend on healthy ecosystems to purify our environment.
Why should we protect endangered animals?
There are several reasons why we need to protect them from extinction. One of the most important benefits of preserving the endangered animals is economic benefit.
