1. BP is using Corexit, a chemical found in dispersants to clean up the oil. However, this chemical is extremely toxic and has a large variety of effects on marine life, etc. The toxins get into the water and the oil, and the fish and plankton can be greatly effected. The small microorganisms eat the dispersants and leftover crude oil and the larger fish that eat plankton also ingest the oil and toxins. This will all go up the food chain and can affect all kinds of marine life.

2. It depends on the situation whether solving a problem or not will create another one. For example, BP used dispersants to break up the oil. While it got the job done faster, it contained toxins that affected the life in the gulf drastically.

3. From the information in the article and the video, I believe that oil spills are more of a problem. While chemical dispersants are extremely toxic, so is oil, and there was a lot of it put in the gulf.
