Oil Spills Escalated in This Decade
Experts: Red flag wasn't heeded
By Alan Levin
The number of spills from offshore oil rigs and pipelines in U.S. waters more than quadrupled this decade, according to government data. The trend could have served as a warning for the massive leak in the Gulf of Mexico, safety experts say.
This would have come in handy when the White House was announcing plans to encourage more offshore drilling. Instead we got assurances like this from USA Today's editorial page:
Some of the most ironic objections come from those who say offshore exploration will destroy beaches and coastlines, citing the devastating 1989 Exxon Valdez oil spill in Alaska as an example. The last serious spill from a drilling accident in U.S. waters was in 1969, off Santa Barbara, California.
