But Jackson's biggest applause line came when we said she was "proud" of the EPA's declaration Monday that greenhouse gases endanger public health and welfare. "That is a decision that has been a long time coming," she said to a packed crowd in the U.S. Pavillion. Jackson said that in light of the scientific finding, the EPA is obligated "to take reasonable efforts to reduce greenhouse pollutants under the Clean Air Act."Read more about Jackson's speech here.
