Why are we drilling in 5,000 feet of water in the first place?

"Why are we drilling in 5,000 feet of water in the first place? Many reasons, but this one goes unmentioned: Environmental chic has driven us out there. As production from the shallower Gulf of Mexico wells declines, we go deep (1,000 feet and more) and ultra deep (5,000 feet and more), in part because environmentalists have succeeded in rendering the Pacific and nearly all the Atlantic coast off-limits to oil production. (President Obama's tentative, selective opening of some Atlantic and offshore Alaska sites is now dead.) And of course, in the safest of all places, on land, we've had a 30-year ban on drilling in the Arctic National Wildlife Refuge. So we go deep, ultra deep -- to such a technological frontier that no precedent exists for the April 20 blowout in the Gulf of Mexico." --columnist Charles KrauthammerMore: http://patriotpost.us/edition/2010/06/02/chronicle/print/
