The advances of the Industrial Revolution tarnished Malthus's theories. This did not deter environmentalists from continuing to promulgate doomsday predictions, though. In 1968, the Sierra Club published a book by Paul Ehrlich entitled The Population Bomb . In a Malthusian replay, Ehrlich forecasted ecological catastrophes. And just as in the case of Malthus, the devastation never materialized.
Statistics show that the current population growth is slowing.
Yet people forget the dire predictions that were never fulfilled. As a consequence, the public remains receptive to warnings concerning a multitude of new crises that demand our urgent attention. As would be expected, PEB assigns blame for environmental problems that exist in the United States on population growth. In fact, the more extreme activists in the environmental movement share a belief with traditional Christians. Both agree that human beings are evil.
