I donated to providing medical health because, I am from one of the places that was listed for the descriptions. I think it's important because there are people in the world that don't get the medical hep that they need. So I try to donate a lot of coins to try and help those people. If people don't get the medical help they need, safe places to live don't need to be built because nobody will be there to live in that place. And protecting the Earth, how can we if everybody is sick? So providing medical health is the foundation to the other two. Thanks for looking at my comment!
