History of Life on Earth

The history of life on Earth has been a history of interaction between living things and their surroundings.


To a large extent, the physical form and the habits of the Earth’s vegetation and it’s animals life have been molded by the environment.


Considering the whole span of earthly time, the opposite effect, in which life actually modifies it’s surroundings, has been relatively slight.


Only within the moment of time represented by the present century has one species – mankind – acquired significant power to alter nature on the Earth.


It took hundreds of millions of years to produce the life that now inhabits the Earth – eons of time in which that developing and evolving and diversifying life reached a state of adjustment and balance with its surroundings.


The most alarming of all man’s assaults upon the environment is the contamination of the air, earth and water with dangerous and lethally toxic materials.


As Albert Schweitzer has said, ‘Man can hardly even recognize the devils of his own creation.’


Given time – time not in years but in millennia – life adjusts and a balance has been reached.


For time is the essential ingredient, but on this modern Earth there is no time.


– Rachel Carson, biologist and author, Presidential Medal of Freedom recipient




“The land itself is in mourning – its wilderness pastures are dried up. For they all do evil and abuse what power they have.” – Jeremiah 23:10
