When chemical dispersants are sprayed onto the oil that’s floating on the surface of the Gulf of Mexico, it makes the oil disperse into the water. It makes it sink.
Whether the oil that has been changed into tiny droplets by the dispersants will then be rendered harmless by natural organisms … or it will coat the ocean floor and cause further damage to underwater creatures … all depends on which group of scientists you are listening to at the moment.
Whatever dispersants do, good or bad, it’s my guess that BP loves them for yet another reason. Once sprayed by the dispersants, the black, shiny, OBVIOUS oil sinks out of sight … and out of mind. And the news media stops writing about it, and people stop thinking about it.
Let’s see, now, what were we talking about? /Gary
