Greenpeace activists protest as Brazil's President Luiz Inacio Lula da Silva speaks during a ceremony at the Ulysses Guimaraes Convention Center in Brasilia August 31, 2009. Lula on Monday said the exploration risk of the massive offshore subsalt oil fields are very low, during a presentation of a bill to reform Brazil's 1997 oil law. Brazil's government proposed on Monday a new law that will determine how it taps and manages huge crude reserves miles below the ocean's surface that it sees driving the nation's rise to developed status. The banners read, "Pre-salt is Pollution: Can't speak of one without speaking of the other". REUTERS/Roberto Jayme (BRAZIL BUSINESS POLITICS ENERGY ENVIRONMENT CONFLICT)
