CE1 International Section students have been learning about Earth Day. This holiday was first started in 1970 in the US because people were becoming concerned about the pollution and the impact it was having on the environment. Now, it is a global holiday with more than a billion people celebrating it every April 22nd . Students discussed what they could do to help protect their community. They made posters and wrote what they could do to help protect the Earth. Here is an example of what the students made.
