Cavemen(穴居人) often ate raw(生的) meat. They didn’t cook their food. Now there are many things to help you cook. In 2050, there will be house robots. They will cook and wash the dishes.
There were many trees and many clean rivers before. Now, there are more and more buildings. We should help the Earth now. So birds will have homes and the forests will be healthy and green again.
Before humans lived on the Earth, whales had already lived in the sea. Now, there are not many whales. If we change now, whales and humans will have a bright future.
