Hard target

Greenpeace hates organochlorines—PCBs, dioxins and hundreds less well
known. In Pandora’s Poison, biologist and ex-Greenpeace research
co-ordinator Joe Thornton lays out evidence against them, putting the case for
more benign alternatives to replace them. Lucid and persuasive. Published by MIT
