Extinction happens when all of the animals or plants of one kind die and there are none left in the world. They disappear forever and cannot come back. Many things can make animals and plants go extinct.
One big reason is losing their homes. This happens when people cut down too many trees or make the water dirty. Animals and plants need these places to live, find food, and have baby animals or plants.
When people hunt or fish too much, it can also cause extinction. If people take too many animals from the wild, soon there will not be enough animals left.
Pollution makes the air, water, and ground very dirty. This dirtiness can make animals and plants sick, and sometimes they cannot survive.
We can help stop animals and plants from going extinct. We should take care of their homes by not cutting down too many trees and keeping water clean. We should not hunt animals too much or take too many fish from the sea. Planting trees and cleaning up trash are good ways to help. If we do these things, we can keep animals and plants safe and healthy.
