Why would life on earth be impossible without green trees?

Well there would not be any carbon dioxide to breathe and no fruits and nuts will be grown and there would be no wood to use when you go camping there would be no fire it would be very cold and dark I love trees and people please wish we will get to keep the trees that are in our yards and different places and you would not have any more Apples,Oranges,grapes,lemons,tangerines,

mangoes,kiwi,or

any fruit and have you not notice that there will not be any plants on EARTH.....................
