And somehow for me, it's captured in words of somebody that I admired very much. She was a mentor of mine, she was a friend, she died much too young, she was an extraordinary personality, a great champion of the environment: Wangari Maathai. Wangari said once, "In the course of history, there comes a time when humanity is called upon to shift to a new level of consciousness, to reach a higher moral ground." And that's what we have to do. We have to reach a new level of consciousness, a higher moral ground. And we have to do it this year in those two big summits. And that won't happen unless we have the momentum from people around the world who say: "We want action now, we want to change course, we want a safe world, a safe world for future generations, a safe world for our children and our grandchildren, and we're all in this together.
