You might be interested in reading about ecopsychology. I was trained as a Biologist and can relate to this. There is no separation between nature and a human's needs; we have the same needs.

Thanks Catherine for your suggestion. But my question was not focused on human in a psychology way. I wish to study what is the state of the art in science about this topic but I'm focus on wich organization or technology the human can take from nature to apply in human life: for example replicate some good nature's solution for some tencological human challenge. In this moment I'm trying to applicate the nature's architecture of an ecosystem to agricultural chains, to make themo more efficient and sustainable linking each other and reducing wastes (in nature doesn't exist this concept but what is output for someone it become input for someone else..in the net of life...).

Sorry but...nothing psycological!

Thanks anyway!!
