Earth Day: April 22nd.

Hello everybody,
Earth Day falls on  April 22nd each year. One billion people around the world celebrate this day across more than 190 nations. It's a worldwide movement with an objective: to spread awareness of environmental protection.
It was celebrated for the first time in 1970. 2020 is the 50th anniversary.
On Earth Day we learn how to take care of this planet and protect it.
It's really important to take responsibility. Are you at home? This is what you can do.
Earth Day at home.
