During the mid 80's decade of twentieth century, the negative aspects of development were discussed at large. Which one among the following was NOT such important ?

The correct answer is C) Politics and Development. In the 1980s the development debate turned to its costs: ecological damage, pollution and the uprooting of people. Bhopal (1984) became the symbol of industrial pollution, the Narmada projects brought displacement and rehabilitation into public debate, and the Brundtland Report (1987) popularised sustainable development, asking whether today's growth is eating into tomorrow's resources.

• A) Degradation of natural resources was a core negative aspect, covering deforestation, soil erosion and depletion of groundwater.
• B) Environment pollution was central to the debate, and it led to the Environment (Protection) Act, 1986.
• D) Displacement and Rehabilitation of masses was a major concern, seen in large dam projects such as Narmada.
• C) Politics and Development names a field of study about how power shapes development choices. It was not a recognised negative consequence of development in the sense the question asks.

Core concept: the externalities of development and the rise of sustainable development thinking. This links directly to Mains GS-I and GS-III on displacement, environment and sustainable development.

Trap: candidates pick politics because it sounds like a cause of bad development, but the question asks about the negative outcomes that were debated, not the discipline that studies development.
