Eric Rodger Pianka[1] (born 23 January 1939) is an American biologist, whose work includes herpetology and evolutionary ecology.[2] His textbook, Evolutionary Ecology (1983) is considered a classic, and his writings for the general public and television appearances have made him an influential figure.[ci

"I have two grandchildren and I want them to inherit a stable Earth. But I fear for them. Humans have overpopulated the Earth and in the process have created an ideal nutritional substrate on which bacteria and viruses (microbes) will grow and prosper. We are behaving like bacteria growing on an agar plate, flourishing until natural limits are reached or until another microbe colonizes and takes over, using them as their resource. In addition to our extremely high population density, we are social and mobile, exactly the conditions that favor growth and spread of pathogenic (disease-causing) microbes. I believe it is only a matter of time until microbes once again assert control over our population, since we are unwilling to control it ourselves. This idea has been espoused by ecologists for at least four decades and is nothing new. People just don't want to hear it... I do not bear any ill will toward humanity. However, I am convinced that the world WOULD clearly be much better off without so many of us... We need to make a transition to a sustainable world. If we don't, nature is going to do it for us in ways of her own choosing. By definition, these ways will not be ours and they won't be much fun. Think about that."
