Let us return to the address to the American Association for the Advancement of Science given in 1967 (later published in Science), by medieval historian Lynn White Jr. He threw down the gauntlet. The son of a Presbyterian minister and himself a lifelong active Presbyterian, White felt nevertheless that his religion had given rise to much that needed answering. “Christianity bears a huge burden of guilt.” White’s thesis is relatively straightforward. Modern science and technology – and the appalling environmental consequences – are the children of the Christian faith. But we get ahead of ourselves. Let’s plunge right into looking at some of these environmental consequences, using as our exemplar the most pressing environmental issue of them all: global warming.
