Thinking reasonably about these topics it should be considered pretty common sense that the things we are doing to our planet are less desirable for its health than if it was left "alone".
I completely agree.
But because we are part of the natural world and happen to be the creature at the top of all the other creatures we are "designed" to leave a big mark on this planet.
And our design does not go very well with leaving other things and creatures "alone" or at peace. We really enjoy being at the top and like to stay there.
No matter the cost....
