David Suzuki is a climate warrior, as his new book, Just Cool It (co-authored by Ian Hanington), attests. He inhabits a Manichean world of virtuous environmentalists and heartless "anti-environmentalists"—people who spread "lies" about climate science, "promote fossil fuels at the expense of human life," and "hold us back from creating a safer, cleaner, and more just world." Just Cool It is chock full of tips for averting "catastrophic global warming" (drive less, eat less meat, etc.) but what Suzuki really wants—what he has always wanted—is to overthrow "our outmoded global economic system." He is an unapologetic radical, but his true gift is to make revolution sound as easy as recycling.
