Gravity
oxygen...we cant live without it
He eats everything edible
One of the living things is trees. Without trees we can not breathe.
Because they want the attention without the tittle of being called a hoe or something mean. I am not completely sure why they do what they do but we cant live without them and definitely cant live with them. :)
i cant live without you
i cant live without u
They can and did live quite happily without it.
you cant live without water or air
They can.
Because there is no air, water or living organisms to eat in space but there is on earth.
without global warming you cant live because without it you wouldn't have enough heat kept in the earth. he earth would be cold... but with greenhouse layers there's too much heat kept in or protected .. so this melts icecap's. etc.
Without gravity we could not stay on the surface of the Earth -- but that wouldn't matter, because gravity is what keeps the Earth from flying apart.
