One of the largest recent environmental disasters is the explosion of Chevron's Deep Water Horizon in the Gulf of Mexico. The disaster caused environmental harm as well as harm to coastal industries. Even though the oil industry promised it knew what to do in-case of a disaster, they did not. There was no investment made by oil companies in research and technology to deal with the spill even though oil spills have been a common occurrence. Due to this lack of investment, old techniques such as using toxic chemicals was used causing more harm as the oil reached the shore.
