This week, as the White House issued a landmark report detailing the frightening affects of global warming on our country and President Obama took to the airwaves to drive home that message, Bill Moyers talks with a scientist who has sounded the alarm for decades.

For nearly 35 years, David Suzuki has brought science into the homes of millions on the Canadian television series, The Nature of Things. He has become a godfather of the environmental movement, and in a poll of his fellow Canadians last fall he was named that country’s most admired figure. Nonetheless, his outspoken views on climate change and the government’s collusion with the petrochemical industry in developing Canada’s oil-rich tar sands have made him the target of relentless attacks from his nation’s prime minister, corporations and right-wing ideologues.

“Our politicians should be thrown in the slammer for willful blindness. …I think that we are being willfully blind to the consequences for our children and grandchildren. It’s an intergenerational crime,” Suzuki tells Moyers.
