As oil prices continue to reach record highs, the search for new sources of energy has led the world to Alberta, Canada, and its vast oil sands. Now, John Vidal finds, the country famed for its wilderness and clean living finds itself caught between fuelling the world's oil-hungry economy and the ecological devastation and soaring greenhouse gas emissions that exploiting the tar sands produces
The Caterpillar 797B heavy hauler is the world's biggest truck. It's taller than a four-storey house, as wide as a tennis court and it removes nearly 35,000 tonnes of oily sand a day from a deep open cast mine in northern Alberta in western Canada.
Truck number 108 is driven by Norman Johnson, 63, a long-time Shell man who is planning to spend his retirement fishing, camping and "hunting the critters" in the vast boreal forests and bogs that stretch across the region. "It's just like driving your car. Couldn't be easier - once you get used to its size," he says from his cab, 40ft off the ground. He won't let the Guardian start up either of its two great engines.
But the future of northern Alberta's aspen and pine woods, its rivers and animals are in doubt as the world's greatest modern oil rush accelerates. Shell, Chevron, Exxon, Total, Occidental, Imperial and most other oil majors have so far invested nearly $100bn Canadian dollars (£50bn) in the 1,160 square mile (3,000 square kilometre) "bitumen belt", which is being called the "new Kuwait".
