The facts and figures may not sound very exciting but all you need to do is look around you and you can see the everyday wonders of our planet. From the vast biodiversity (the Earth is home to many different animals, plants, and other living things!), the dynamic weather, and the rich culture that we practice, our home is a wondrous planet and there's none like it in our solar system.
However, all life on Earth is threatened by some of the things that we do. Pollution from our cars and factories, thrash from all the things we buy then throw away, loss of forests and jungles to build cities and homes; we have done a lot to damage our planet but it's not too late to save it.
For April, you have a chance to earn the PLANET PROTECTOR badge by telling us how you protect the planet Earth! Tell us what you have done in the past, are currently doing, or plan to do to help save our planet.
