Barry Commoner - The Paul Revere of Ecology

Barry Commoner was an American biologist, college professor, politician. and a leading ecologist among the founders of the modern environmental movement. 

In 1970, the year of the first Earth Day, Time magazine put Dr. Commoner on its cover and called him the Paul Revere of Ecology.

His 1971 bestselling book ‘The Closing Circle’, was one of the first to bring the idea of sustainability to a mass audience. His book listed 4 laws of nature.

    Everything is connected to everything else. There is one ecosphere for all living organisms and what affects one, affects all.

    Everything must go somewhere. There is no "waste" in nature and there is no "away" to which things can be thrown.

    Nature knows best. Humankind has fashioned technology to improve upon nature, but such change in a natural system is "likely to be detrimental to that system"

    There is no such thing as a free lunch. Exploitation of nature will inevitably involve the conversion of resources from useful to useless forms.

These laws have never been repealed and are still in effect even thought mostly ignored by our modern, so called, scientific community.  As a society, it would behoove us to pay more attention to these laws of nature.
