The ______ Commission established by the United Nations Organization in 1986 studied world's environmental problems and propounded the notion of ' sustainable development':
Understanding the 1986 UN Environmental Commission
The question asks about a specific commission established by the United Nations Organization (UNO) in 1986. This commission was tasked with studying the world's environmental problems and is credited with introducing the crucial concept of 'sustainable development'. Understanding the origins and definition of sustainable development is key to addressing global environmental challenges.
Identifying the 'Brunoltland' Commission
The options provided are Copanhegan, Brunoltland, Onio, and Kyoto. Based on historical context and the options given:
- The commission established by the UN that focused on environmental issues and popularized the term 'sustainable development' is known as the Brundtland Commission.
- This commission was officially called the World Commission on Environment and Development (WCED).
- It was chaired by Gro Harlem Brundtland, hence the common name 'Brundtland Commission'.
- Although the question mentions 1986, the commission was actually established in 1983 and released its influential report, "Our Common Future," in 1987. The report defined sustainable development as "development that meets the needs of the present without compromising the ability of future generations to meet their own needs."
- Therefore, the option 'Brunoltland' directly relates to this significant commission.
Analyzing the Options
Let's look at why the other options are less likely:
- Copanhegan: This does not correspond to any known major UN commission related to sustainable development.
- Onio: This option is also not associated with the UN commission that defined sustainable development.
- Kyoto: The Kyoto Protocol (established in 1997) is a significant international treaty related to climate change, aiming to reduce greenhouse gas emissions. While related to environmental issues, it is distinct from the commission that originally propounded the concept of 'sustainable development' in the mid-1980s.
The Brunoltland Commission is the correct answer as it directly refers to the Brundtland Commission, the UN entity established around that time that profoundly shaped the understanding of sustainable development and global environmental problems.
