The UK's King Charles has written a children's book. It is called "Climate Change". Charles is an environmentalist. He speaks about the environment a lot. He hopes his book will teach children about nature. The other writer of the book wants to give children facts. He said children must find answers to climate change for their future.

Last Friday, Charles asked business leaders to help protect nature. He said he was excited because children want to help the Earth. Charles loves "the level of energy and passion [for nature] shown by young people". Charles wrote: "Ever since I was a young teenager, I have been deeply worried about…our world."
