Well according to what scientists say, they are what helps us survive and I suppose if you look deeply enough about anything then that's true, apart from the fact they give off oxygen and store carbon dioxide I think we couldn't live without them. Especially with the amounts of carbon monoxide released in central cities, the best idea is, to plant a tree in the central parks. It could make a difference. All in all the answer is yes.
