All living beings, not just animals, but plants and microorganisms, perceive. To survive, an organic being must perceive – it must seek, or at least recognize, food and avoid environmental danger. – Lynn Margulis
There is no scientific reason to think that we, even with space travel, are going to survive as a species for ever, certainly not by biting off the hand that feeds us, which is exactly what we are doing. – Lynn Margulis
