Undersea crude oil has gushed into the Gulf of Mexico near Louisiana since a fiery, deadly drilling accident April 20, and experts still were struggling to control the massive gusher as this week began. British Petroleum (BP), the main drilling company involved, is trying many ways to contain the gooey mess and skim it off coastal waters.

With the environmental disaster entering a second month Tuesday, the toll on marine life, birds, beach resorts and commercial fishing for shellfish and other catches is escalating daily. Louisiana license plates say "Sportsman's Paradise," but there's a huge economic cloud in paradise. Tourists are canceling hotel and charter boat reservations. Restaurants and supermarkets around the country are switching to farm-raised shrimp from South America or Asia as shortages already boost the cost of Gulf supplies.

In the scramble to stop the pollution, BP on Monday reported "good progress" threading a mile-long, six-inch tube with a rubber stopper into the 21-inch pipe spewing oil from the ocean floor. "We're really pleased that we're capturing some of the flow," a top executive said. The company hopes to halt the flow in about a week. In another new move, federal officials let BP spread chemicals underwater to break the oil into small drops and prevent it from reaching the surface or shore.
Cleanup efforts at the surface include controlled burning, skimming and an offbeat new tactic -- deploying nylon "booms" filled with donated human and pet hair that absorbs oil readily. (See video below.) An underwater strategy not yet attempted involves plugging the open pipe with bits of tires, golf balls and all kinds of junk -- sort of like purposely clogging a sink or toilet.

President says: "I'm not going to rest or be satisfied until the leak is stopped at the source, the oil in the Gulf is contained and cleaned up, and the people of the Gulf are able to go back to their lives and their livelihoods." -- President Obama, May 14 at White House

BP head says: "You can't have an incident of this seriousness and not expect significant changes [in drilling rules] as a consequence." -- Tony Hayward, chief executive
