Rio Report: Return of Severn Cullis-Suzuki

Our colleagues at Green Cross International hosted "Green Cross Day" on June 16 in Rio, where we are gathered for the Rio+20 United Nations Conference on Sustainable Development. The closing remarks were given by Severn Cullis-Suzuki, 20 years after she made an impact at the 1992 Earth Summit -- when she was only 12 years old.
