Didn't they dump tons and tons of chemicals to break up the oil spill, rather than spending the time and money to actually clean it up?

Not antagonizing but curious: how else would you do it?

Those aren’t mutually exclusive - time and money were spent to dump tons of dispersants in an effort to actually clean it up. This comes after the Exxon Valdez spill where it was learned that hot water and high pressure hoses to clean areas did more damage than good - the untouched beaches recovered faster via natural breakdown than the beaches that were cleaned. In deepwater, they skipped the scrubbing and cleaning and emphasized dispersants (y’know, solution to pollution being dilution) and it probably hurt the ecosystem more than letting natural enzymes and such take care of it. The bottom line is that every major oil spill clean up effort is an experiment. But sometimes the instinct to “do something” causes more harm than good. Would the public tolerate an “all natural” approach or a light touch of beach cleaning? Probably not, even though there’s good reason to think the ecosystem (exclusive of human needs) may be better served by that.

break it up? no. it just made the oil heavy enough to sink. it's all still there, just at the bottom of the ocean now
