Answer 1

Hint:- Global warming, depletion of natural resources, pollution, habitat destruction, and the ever-increasing human population are some of the causes of environmental destruction. The United Nations (UN), an international organization, with all its member nations, aims to revert the situation and encourage sustainable development. The organization has held conferences wherein member nations all called to discuss, agree, and implement corrective measures in their respective countries.

Complete Answer:-
The Earth Summit, a conference organized by the United Nations, is held every ten years. The third Earth Summit was held in Rio-de-Janeiro. It is also called the United Nations Conference on Environment and Development (UNCED). Representatives from nations had participated in the conference to discuss their concerns regarding the environment and sustainable use of resources.
The conference was able to shed light on major environmental concerns. Agenda , an action plan adopted by some member nations aims for sustainable development on a local, national, and global level.
Treaties, such as the Kyoto protocol, were signed by the member nations. The individual governments had to work to reduce the emission of greenhouse gases (carbon dioxide, hydrofluorocarbons, etc).
The Biodiversity Convention another treaty signed that aims to conserve biodiversity. Issues, such as the shortage of water and alternate resources of energy or fuels were also addressed in the conference.

The correct option is (C), The Earth Summit at Rio-de-Janeiro was related to the conservation of the environment.

Note:- In 2012, Earth Summit was again held in Rio-de-Janeiro. This summit was called the United Nations Conference on Sustainable development (UNCSD).
While the UNCED did bring attention to the major environmental concerns, all the treaties signed were not implemented well in most nations. Many developed nations did not reduce their consumption of natural resources nor did they reduce the emission of greenhouse gases. However, efforts are still being made by individuals and organizations to change the present scenario.
