Our planet is an amazing place, filled with living seas, towering mountains, and incredible wildlife. But we need to take better care of our world. Every day, we do things that harm the environment. We burn too much coal and oil, which produces harmful gases. These gases rise up into our atmosphere and cause global problems. We scrape away too much rock from our mountains to harvest minerals. We cut down too many trees in our already dwindling forests. We send out fleets of fishing boats that comb the seas for more and more fish.

These are big problems that we can all try and change through the decisions we make every day. These decisions can help improve things for the future. Try the following experiments to learn what is happening to the Earth and what you can do to help.
