The United Nations Conference on Environment and Development (UNCED), also known as the Earth Summit, took place in Rio de Janeiro in 1992. It brought together representatives from over 170 countries to discuss global environmental issues and sustainable development. The conference aimed to address challenges like deforestation, pollution, and climate change, promoting cooperation among nations. One of the key outcomes of the Earth Summit was the adoption of the Agenda 21, a comprehensive plan for sustainable development. Additionally, the conference led to the establishment of important agreements, including the Convention on Biological Diversity and the Framework Convention on Climate Change, which continue to influence environmental policies worldwide.
