Mother Nature?

how is it that when we derive everything--our survival, our comfort, our riches--from nature (think:water,electricity, diamonds, fuel, steel) and yet we continue to destroy it? why are we killing the goose that lays the golden egg? Or cutting the branch that we sit on?
We rape the forests, gouge the mountains, poison the waters, kill the river, slaughter the wildlife, pollute the air, pillage the valleys, flatten the hills.
We degrade, destroy kill Nature.
and we call her mother.
