Question

Extinction occurs when all the members of a species completely die out. Both human activity and natural causes can lead to the extinction of a species.
Human activity is a major cause of recent extinction. As humans multiply, they often harm or destroy the habitats of other animals, which can lead to extinction. Hunting animals for food is also a practice that has led to the extinction of some animals.
Natural causes, such as competition, predation, and climate change, can cause a species to become extinct over a long period of time. Other types of natural disasters include events such as an asteroid strike or a flood. These types of natural causes can have an immediate effect.
