From the cranberry cancer scare of the 1950s to the Alar-in-apples hysteria of the 1980s, from the "new ice age" of the 1960s to the "global warming" of the 1990s, environmental alarms almost always turn out to be false. Few non-political scientists fear ozone loss, global warming, or acid rain. These are just issues that some people hope to use to reorder the lives of the rest of us.
