Environmentalist Convinced by Obama - Drilling is O.K.
 The 1969 Santa Barbara oil spill was a galvanizing moment for environmentalists. It helped launch the modern environmental movement and gave us a new symbol of environmental threat - the offshore oil platform. But a lot has changed in the past four decades. The technology of oil drilling has made huge advances. New environmental threats have emerged - most important, global warming. The time has come for my fellow environmentalists to reassess their stand on offshore oil. Awright! AGW is now used for something useful! It is not clear that the risks of offshore oil drilling still outweigh the benefits. The risk of oil spills in the United States is quite low. One result of the 1969 oil spill is that we have detailed records on every oil spill into U.S. waters greater than one barrel and comprehensive studies of the sources of oil in marine waters throughout the world. From 1971 to 2000, offshore facilities and pipelines were responsible for only 2 percent of the oil in U.S. waters. The bulk of it (63 percent) came from natural seepage, and 22 percent came from municipal and industrial runoff. Worldwide, natural seepage is the largest source (47 percent) of oil in water, followed by spills from ocean transportation (33 percent). In short, the risk of oil spills from platforms is small.  In contrast, there are relatively high environmental costs associated with importing oil as opposed to producing it in the United States. There are three problems with importing oil: First, spills from tankers and barges are the largest human-caused source of oil in the oceans. Oil is more likely to be spilled from a tanker than from a platform, and tankers have the potential to cause catastrophic spills. The groundings of the Exxon Valdez (off Alaska), the Castillo de Bellver (South Africa), the Amoco Cadiz (France), the Irenes Serenade (Greece) and the Torrey Canyon (Britain), to name a few, all had severe effects on local ecosystems. Tankers are harder to shut off than a pipeline. Second, the countries from which we import oil have lower environmental standards than the United States has. Bingo. Give that man a prize for figuring it out. In particular, many foreign oil producers choose to vent methane a powerful greenhouse gas - directly into the atmosphere rather than spend extra money to capture or flare it. Mexico, for example, produces less than half the oil that the United States produces but emits six times as much methane. Now, if crystal meth was made from methane... Third, shipping oil to the United States requires burning a huge amount of diesel oil, the exhaust from which is greenhouse gas pumped into the atmosphere. Just as environmentalists argue that eating locally grown food is better for the planet because it saves transportation costs and energy, locally produced oil has less of a negative impact. Depending on the country of origin and the tanker size, 1 percent to 3 percent of the oil in every tanker is consumed merely for delivery. Or, we could use nuclear-powered tankers! In 1969, we had many reasons to fear offshore oil drilling. But in the past four decades, offshore oil has become far safer, and our country faces new environmental risks. The real question about drilling off our coasts can be settled by due diligence: How much greenhouse gas is released into air when we drill for oil along our coasts, and how much is released when we import it? A rigorous study should be conducted to find out. If assessments show that domestic oil production contributes less to global warming, environmentalists should support it. We should not be living in the past. Aha. Guess who wants the grant money? The writer is a professor in the political science department at the University of California at Santa Barbara. He is affiliated with the university's Bren School of Environmental Science and Management and the environmental studies program. Wow. A California environmental professor awakened by Global Warming.
