Anyone remember the opening salvos in the fight against the US spraying DDT to control mosquitoes, gypsy moths and other pests? The US govt used the now familiar "science deniers" argument against the citizens who brought suit against the US govt to stop spraying DDT in the Long Island area. The govt legal team and the govt scientists agreed that DDT could be found in the fatty tissue of many Americans but they also said that DDT was harmless to humans. Those who disagreed were, of course, science deniers.
