Now there are many things to help you cook.
In 2050, there will be house robots. They will cook, clean and wash the dishes.
Oh, cavemen didn’t cook their meat
It’s OK. They didn’t do the dishes either!
There were many trees, and there were many clean rivers.

We should help the earth now, so birds will have homes and the forests will be healthy and green again.
Look! How beautiful the world was! Oh! What will the birds do
Don’t worry. People
