Here are several Wall Street Journal
articles about industries that are affected by the BP oil spill.
Some of the industries devastated by the BP oil spill are: the U.S. seafood industry; the U.S. tourism industry in the states of Louisiana, Alabama, Florida and Mississippi; the U.S. offshore drilling industry; the restaurant industry in the four states previously mentioned (also restaurants in other states may be affected if the cost of seafood rises); the wildlife and fisheries industries in the four previously mentioned states; the oil and gas industries; the real estate market (especially for waterfront properties in the states along the U.S. Gulf Coast); etc.
However, there's no doubt that the BP oil spill is resuscitating the legal profession on both sides of the pond - generating lots of legal work in the U.S. and the U.K.!
I grew up in New Orleans and have an office in Miami. So I know from first hand experience how these industries are being devastated by this oil spill. Also, who knows what this oil spill will do in the long term to the environment and the health of the people living, working and drinking the water in these affected areas.
I truly hope - for all the parties involved on both sides of the pond - there is a good ending to this very sad story!
