Since 1991, oil production on U.S. land and in Alaska has dropped 40 percent, but it has nearly doubled in the Gulf of Mexico, according to federal statistics. A 2008 International Energy Agency report estimates that reachable conventional oil located in water more than a quarter-mile deep is between 160 and 300 billion barrels, with more than two-thirds of that in Brazil, Angola, Nigeria and the United States. "Our energy security is going to hang on whether we can drill offshore," said Amy Myers Jaffe, an energy studies fellow at Rice University's public policy institute. So what are the costs? It starts with the possibly devastating oil spill unfolding right now off the coast of Louisiana. McKinney's research institute in Corpus Christi estimated a worst-case scenario cost of the spill to the Gulf of Mexico: $1.6 billion. About one-quarter of that is due to lost fishing and tourism. But the bulk of the cost is in the stuff that's less easy to quantify: the general wetlands ecology. If half a million acres of wetlands are severely damaged, that drastically affects a fragile area that acts as a wastewater treatment plant for water flowing out of the Mississippi River
-- where 40 percent of America's water flows into. And every acre of wetland means one less foot of storm surge from a hurricane, he said. McKinney worries that this is "strike three" for the Gulf's wetlands. First, they've been shrinking because of development and engineering changes to natural drainage in Louisiana. Then Hurricane Katrina damaged them. And now this. "This one is getting all of us worried," McKinney said.
But that's not all, environmentalists point out. There are lives lost in getting oil and coal. Another coal miner died in an accident Tuesday in West Virginia, that's in addition to the 29 who died in a massive explosion April 5 in that state and an accident last week that killed two in Kentucky. Besides the accidents, more than 29,000 workers have died of coal mining-related lung diseases since 1968, according to the federal government. The BP PLC oil rig explosion April 20 that caused the spill also claimed 11 lives. That came only weeks after an April 2 refinery fire in Washington state that killed seven workers. In 2008, work accidents killed 120 people in the oil and gas extraction industry, according to the U.S. Department of Labor. Add to that global warming. Burning oil and coal produces carbon dioxide, which scientists say is changing the Earth's climate and will eventually change the life of nearly everyone on the planet. This year, after what seemed like a cool winter in some spots, the heat is back on. Already it's shaping up to be one of the warmest on record, with a record-setting March, according to both government weather statistics and those kept by global warming skeptics at the University of Alabama Huntsville. "What we're seeing is proof positive of our dependence of oil and gas, and we've ignored that in the past," McKinney said. "Unfortunately it's being rubbed in our face right now."
