In my opinion, the best charity to donate to is the "Protect the Earth" one! I've already donated about 20,000 coins to it! The reason that I think the "Protect the Earth" is the most important is because, without a healthy Earth, the other two would be a waste! You need a healthy Earth to have good homes, or good medical protection! Also, with Global warming becoming a big threat and Pollution being the cause of it, we should try harder to protect the Earth before trying to help the Medical help and Building new homes!
