FACED with rising anger from environmentalists last year over his plans for a transcontinental pipeline to deliver treacly Canadian tar sands to Texas oil refineries on the Gulf of Mexico, the CEO of TransCanada, Russ Girling, expressed surprise. After all, his company had laid 300,000 kilometres of such pipes across North America. "The pipeline is routine. Something we do every day," he told Canadian journalists.

But that's the point. It is routine. The oil industry does do it every day. And if it carries on, it will wreck the world.

We need not rely on climate-changing fossil fuels. Alternative energy technologies are available.
