What does it mean when an species becomes extinct?

When a species becomes extinct it means that the last living member of that species has died and that there are no more members of that species left on Earth. It implies the complete termination or disappearance of a particular species from the planet. Extinction is a natural process that has occurred throughout Earth's history, but the current rate of extinction, primarily driven by human activities, is considered to be a significant environmental concern and a threat to biodiversity.
