From Wikipedia, slightly edited:
Deep ecology argues that the natural world is a subtle balance of complex inter-relationships in which the existence of organisms is dependent on the existence of others within ecosystems. Human interference with or destruction of the natural world poses a threat therefore not only to humans but to all organisms constituting the natural order.
Deep ecology advocates wilderness preservation, human population control and simple living.
And:
The deep ecology view argues that human communities are built upon a foundation of the surrounding ecosystems or the biotic communities.
Yes!
