Extinction means that something disappears completely or will never appear again. This word is usually used to describe that something or a phenomenon has never happened in a certain place or period of time, or that something or a phenomenon has completely disappeared and no longer has any impact on people's lives.

For example, we can say that a species has disappeared from the earth, which means that this species has completely disappeared and no longer exists. It can also be said that a pollution source has disappeared in a certain place, which means that this pollution source has never appeared in this place again, and the environment has been completely improved.

Extinction can also be used to describe the complete disappearance or disappearance of an action or idea. For example, a bad habit or thought disappears in a group, which means that no one in this group shows this bad habit or thought again, and some positive behaviors and thoughts are replaced.
