I'm grumpy.

Trees: Ohai guys! Listen, we are going to give you lovely fruits, flowers, and beautiful foliage! You can eat from us, you can seek shade under us, and you can enjoy all the sweet creatures who will make homes in our branches. We're also going to give you life-sustaining oxygen, because, let's be honest, we both know you can't live without it. We don't even want anything in return! How'bout it?

Us: LOL no thx we're just going to cut you down and make paper out of you, to smear on our asses after we shit. 

Conclusion. Trees are better people than people. 

Garumph.
