Why Should We Protect Wild Animals?
Do you know any endangered animals? Why are they in danger?
As far as I know there are many endangered animals in the world, such as tigers and pandas. When
farmers cut down trees, tigers can no longer hide and hunt. Many tigers are killed by people who want
to sell their fur for money. And there are few places where pandas can live.
We are not alone in the world. We human beings could not live without all the plants and animals around us.
So protecting wild animals is very important. We must take measures to keep plants from being destroyed and
stop animals from being killed. We all hope that in the future there will be a lot more forests and wild animals.
