Why is it important to save 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.

How Can extinction be prevented?

The best way to help endangered species is to protect the environments where they live. Give your time to nature by visiting or volunteering at a local wildlife refuge. Such organizations always need donations and volunteers as they often lack adequate funding. Simply visiting a wildlife foundation can help.

Are humans the main cause of animal extinction?

The last confirmed sightings came in the 1660s. The dodo was lost forever.

How will extinction affect humans?

As species disappear, infectious diseases rise in humans and throughout the animal kingdom, so extinctions directly affect our health and chances for survival as a species. The rise in diseases and other pathogens seems to occur when so-called “buffer” species disappear.

What was the first animal to go extinct?
