RIO + 5: RIO EARTH SUMMIT FIVE YEARS LATER

President Clinton recently told the world he will personally lead the U.S. delegation that will attend a special United Nations meeting on the environment next month. Conservation groups, members of Congress and administration officials are now debating which proposals the president should champion at the conference which will tackle issues such as global warming and sustainable development. The conference, to be held at the U.N. in New York, will mark the fifth anniversary of the 1992 Earth Sumit in Rio de Janeiro, Brazil. As John Rudolph reports the international gathering offers Mr. Clinton a chance to make his mark as a world leader on environmental issues.
