How can I boycott BP or help to make it pay all of its profits for compensation claims for years to come?

I am horrified by the catastrophe in the Gulf of Mexico. Every day is the equivalent of an Exxon Valdez. What can I do to boycott BP and help to pub this irresponsible corporation pay for all the damage out of business? It seems BP was cozy with the Bush Department of Justice and there are many crimes that went uninvestigated. What can I do personally to fight this corporation?
