Hopefully never as they are valuable in many ways. Including making much of the oxygen that animals need to live.

Im pretty sure if we use agroforestry we will never run out of trees!

You shouldn't be cutting down trees! But if you cut to many, you run out
Because we need to have oxygen and that comes from trees. So if there are no trees, and someday we will run out, we have no oxygen to breath
Trees are a sustainable material and always will be because you can keep on planting them again and again and they will never run out.
Because we can renew them easily, find them easily and will never run out and or they continue to grow and will not run out example: trees

Plant trees and grasses, and terrace the topography.
