In a plot so devious and underhanded I'm surprised James Bond hasn't appeared yet, BP uses a toxic chemical called (ironically) Corexit to make the oil less visible to planes and boats. By using Corexit, BP is able to pretend that it's cleaning up the oil in record time when it's actually spreading it throughout the ocean and making actual environmental recovery much more difficult. According to three studies, the use of Corexit has increased the toxicity of the oil by up to 52 times. For an extra point, who owns a huge percentage of the company that makes Corexit? Yep, you guessed it. BP.
