Off-shore drilling, or oil tankers? Of course, many “environmentalists” would like to ban both. And have us go back to chopping wood, and forty acres and a mule. As long as we aren’t too cruel to the mule.
But it’s pretty clear to me that off-shore drilling with modern technology is much lower risk, in terms of oil spills, than having foreign-flagged tankers operating in our waters. This kind of false sense of safety, and misplaced priority is common. For instance, some people avoid flying, because they fear it, and drive instead, vastly increasing their risk of being killed on the trip. I don’t know whether people who oppose oil drilling are being similarly irrational, or if they simply recognize it as an easier target than ending oil imports, so they grab whatever low-hanging fruit they can to minimize our oil consumption (and drive up the price, which is perhaps part of the goal).
Also, as noted here, banning drilling off US shores doesn’t eliminate the risk of spills from drilling. It just moves it to other (and perhaps even more environmentally sensitive) places.
