Extinction

Extinction refers to the permanent loss of a species, meaning that no individuals of that species remain alive anywhere on Earth. This can happen due to various factors such as habitat destruction, climate change, pollution, overhunting, and invasive species. When a species goes extinct, its unique genetic traits and ecological roles are lost, which can disrupt ecosystems and affect other organisms. Extinction is a natural process, but human activities have significantly accelerated it in recent times, raising concerns about biodiversity and the health of our planet.
