Theories of extinction

Theories of extinction explore why species disappear. One common idea is environmental change—shifts in climate or habitat can make survival impossible. Another theory suggests overhunting or overuse of resources by humans leads to decline. Disease outbreaks can also wipe out populations, especially if they spread quickly. Additionally, natural events like volcanic eruptions or asteroid impacts can cause rapid extinctions. Often, a combination of these factors contributes to a species' disappearance. Understanding these theories helps us learn how to protect endangered species and prevent future extinctions.
