Oil Spill

 

"This is probably the biggest environmental disaster we've ever faced in this country. It's certainly the biggest oil spill, and we're responding with the biggest environmental response."

Carol Browner, Assistant to the President for Energy and Climate Change

Oil Spills R Us

Besides contributing to quite a number of human ulcers, the Gulf Spill may well be a "gastric" event on a planetary scale! While oil is certainly a "natural substance," it's relatively harmless only where it naturally occurs, sequestered deep in the earth (and in naturally-occurring seeps like the  famous La Brea Tar Pits). Outside of these contexts is another matter. By analogy, think of the damage our stomach acids do when they escape from their own protective enclosure. 

So, how to best deal with an ongoing environmental disaster? We're posting a dozen new and archival programs that we hope can help shed light some light on this matter. Recently, I spoke with Terry Hazen, head of the Ecology Department at Lawrence Berkeley National Laboratory and one of the world's leading experts on bioremediation (using microbes to clean up hazardous waste and oil spills). What he has to say raises many questions. Are we doing enough, or in some cases, too much? Oil-covered pelicans and devastation to the coastal ecosystem certainly call for action, but along with physical containment and cleanup methods, should we be using naturally occurring microorganisms instead of chemical dispersants? According to Hazen, these detergents and dispersants may prove to be a greater detriment than the oil itself. 

It's not the first time we've been in this situation, although not on this scale. Please listen to our archival programs, which sound as though they could have been recorded yesterday. These programs feature interviews with – among others – John Farrington, a senior scientist at Woods Hole Oceanographic Institution; and Chuck Kennicut of Texas A&M University, who – twenty years ago, – said "there needs to be a national policy as well as a national readiness to react to these types of spills in a timely manner" (program #198). We believe these programs are as prescient today as they were when we first aired them.
