to frack or not to frack

In one sense, the analysts who forecast that “peak oil”—i.e., the point at which the rate of global petroleum extraction will begin to decline—would be reached over the last few years were correct. The planet is running short of the easy stuff, where you stick a drill in the ground and crude comes bubbling to the surface. The great oil fields of Saudi Arabia and Mexico have begun to dwindle; one result has been a rising price for energy. We could, as a civilization, have taken that dwindling supply and rising price as a signal to convert to sun, wind, and other noncarbon forms of energy—it would have made eminent sense, most of all because it would have aided in the fight against global warming, the most difficult challenge the planet faces. Instead, we’ve taken it as a signal to scour the world for more hydrocarbons. And it turns out that they’re there—vast quantities of coal and oil and gas, buried deep or trapped in tight rock formations or mixed with other minerals. Getting at them requires ripping apart the earth: for instance, by heating up the ground so that the oil in the tar sands formation of Canada can flow to the surface. Or by tearing holes in the crust a mile beneath the surface of the sea, as BP was doing in the Gulf of Mexico when the Deepwater Horizon well exploded. Or by literally removing mountaintops to get at coal, as has become commonplace across the southern Appalachians.
