I do think trees are more evolve than us. Simply by existing, trees constantly create opportunity for life to grow.
They shelter quantity of animals, feed billions of more or less microscopic living creatures (insects, mushrooms, bacteria), induce rain, create an environment with ideal climatic conditions, prevent landslides, provide us incredible useful resources (wood, fruits, substances for medication)... Not even talking about the air you're breathing. And when they die, it's another cycle of benefits that begins.
Meanwhile we may have invented iPads, but as for now, we are at the exact opposite of trees and only know to live the destructive way.
I wonder how humanity would deal with a 75% of our food supply disappearing by 2050. Cats would certainly take over us...
