Write a note on Earth Summit.

In June 1992, more than 100 heads of states had met in Rio de Janeiro in Brazil, for the first International Earth Summit.

The Summit was convened for addressing urgent problems of environmental protection and socioeconomic development at the global level. The assembled leaders signed the Declaration on Global Climatic Change and Biological Diversity. The Rio Convention endorsed the global Forest Principles and adopted Agenda 21 for achieving Sustainable Development in the 21st century.
