I donated to all three of the cause because in this world, all those pollution already made Global Warming and could make the animal extinct. We need to save the endangered animal so they don't extinct. It would be sad not to learn them. The second one is Providing Medical Health. In some places, disease would spread around. If there is no doctor or any members of the health team, disease or any other illness would spread. We don't want a lot of sick people. Everyone should be healthy. That is why donating coins and build more hospital help most people. The most important thing is build more shelters because in this world, most of the people are homeless. They have no food to eat. No safety. Important thing is no family. We want everyone to be happy, not sad. So that is why I really think Building more houses is way important than the others. Oh ya, if you have a shelter. It will give you a less chance of being sick than homeless people.
