Environmentalists, who put significant pressure on El Obamados during his first term to deny the transnational project a go-ahead, are planning to demonstrate near the White House on Sunday by encircling his residence with a giant inflatable pipeline. (Who says they do not have a sense of humor?) Protestors want the President to make good on his promise to make climate change a priority of his second term. Critics of the pipeline project say it will dramatically increase the nation's carbon emissions by committing it to expanded fossil fuel production from Alberta's tar sands deposits. Supporters see it as a sure route to domestic energy independence. Al Gore, author and climate change advocate, has spoken out against the project, saying that it is the dirtiest source of liquid fuel imaginable and incompatible with reducing emissions causing global warming.
