"Man can hardly even recognize the devils of his own creation" - Albert Schweitzer

"The history of life on earth is a history of the interaction of living things and their surroundings.  To an overwhelming extent, the physical form and habits of the earth's vegetation and its animal life have been molded and directed by the environment.  It is only within the moment of time represented by the twentieth century that one species - man - has acquired significant power to alter the nature of his world, and it is only within the past twenty-five years that this power has achieved such magnitude that it endangers the whole earth and its life."  - Rachel Carson, in the first installment of Silent Spring published by The New Yorker on June 16, 1962, 55 years ago this week.
