Is offshore drilling good for environment?

offshoreHouse Speaker Nancy Pelosi, D-Calif., said that in opposing drilling in the Arctic National Wildlife Refuge and offshore, she was “trying to save the planet.” But columnist Charles Krauthammer contends that “the net environmental effect of Pelosi’s no-drilling willfulness is negative.” He wrote: “Outsourcing U.S. oil production does nothing to lessen worldwide environmental despoliation. It simply exports it to more corrupt, less efficient, more unstable parts of the world — thereby increasing net planetary damage.”
