Without photosynthesis the world would die, we would die, animals will die. If plants did not have photosynthesis they would die because they would have no food, they would not be able to produce sugar or oxygen as animals need oxygen and the sugar is the plants food. If the plants die because they do not have photosynthesis then there is nothing to make sure that carbon dioxide is turned into oxygen and the balance of nature would be tipped. As plants would start to die humans would not be able to breath. Food would not be able to be grown. Also if plants die, then animals die, and if animals die then we humans don't have anything to eat, because animals eat plants and we eat the plants and animals.
I am not sure if we would die of hunger or oxygen first.
It's A Beautiful World
