Twenty years ago, a 12-year-old girl took the podium at the U.N. Conference on Environment and Development in Rio de Janeiro and told a room full of world leaders that they were failing her. "Coming here today, I have no hidden agenda. I am fighting for my future. Losing my future is not like losing an election or a few points on the stock market. I am here to speak for all generations to come," she said. Severn Cullis-Suzuki was only nine when she and her friends created the Environmental Children's Organization, or ECO, a group dedicated to learning about and educating others on environmental issues. The speech she delivered just a few years later at the 1992 Earth Summit captured the world's attention and would in many ways shape her life.
