"Which is the greater danger - nuclear warfare or the population explosion? ..." - Dr. Isaac Asimov

"Which is the greater danger - nuclear warfare or the population explosion? The latter absolutely! To bring about nuclear war, someone has to do something; someone has to press a button. To bring about destruction by overcrowding, mass starvation, anarchy, the destruction of our most cherished values - there is no need to do anything. We need only to do nothing except what comes naturally - and breed. And how easy it is to do nothing." - Dr. Isaac Asimov
