Firstly, I would change the poverty in to wealth in all countries because it's isn't fair when other people already have riches, While some have to bathe in puddles, drink dirty water in there and find some garbage to survive . When they see how good the world is in a normal standpoint where they have a lot of money and the freedom to get and do as they wish. I'd smile when I see them enjoy it and I would change the whole food system everything would be natural, organic and in its most natural state. The problem with the world is all the food we eat changes us as people and it all boils down to the quality of the soil. Everyone not get sick and more one choice that i want to change is every people can talk with all animals and know how they feel what they want else. Finally I wish my world have only happiness thing.
