A journalist, and former roughneck, considers our long, complex, tortured relationship with oil. Oil has dominated our lives for the last century. It has given us warmth, progress, and life-threatening pollution. It has been a gift and is now a threat. It has started wars, ended wars, and infiltrated governments—in some cases, effectively become the government. And now oil's enduring mythology is facing a messy, complicated twilight. In On Oil, Don Gillmor, who worked as a roughneck on oil rigs during the seventies oil boom in Alberta, looks at how the industry has changed over the decades and illustrates the ways our dependence on oil has led to regulatory capture, in Canada and elsewhere, and contributed to armed conflict and war across the world. Gillmor documents the myriad ways that oil companies have misdirected environmental action and misinformed the public about climate concerns and illuminates where we went wrong—and how we might yet change course.
