My thought bubble would include the different ways animals use that tree for their home.

Nature isn't greedy, nature will give us flowers and while we put them in our houses, or we gift them to someone, she will regrowth even more, on and on again. Nature give us trees, allowing us to shelter underneath or find another useful purpose as gaining wood from it. The point isn't us using what nature give us, the problem begins when we take without give back. Plating a tree, avoid to cut it all if unnecessary, leave bigger trees because the smaller ones needs them. Be mindful, that's all.
