What was a significant negative environmental impact of the Green Revolution?

Question

Accepted Answer

Step-by-step explanation:

1. The Green Revolution introduced high-yield crop varieties, heavy use of chemical fertilizers and pesticides, and expanded irrigation to boost production.

2. These practices led to a number of environmental problems, the most direct and widespread being soil degradation: nutrient depletion, salinization and waterlogging from excessive irrigation, and loss of soil structure and biodiversity due to intensive monoculture and agrochemical use.

3. Other options are less accurate as the primary negative impact: deforestation (a) was not a central, widespread consequence of the Green Revolution; increased air pollution (c) was not a primary effect; ozone layer depletion (d) is unrelated to the Green Revolution’s agricultural practices.

Therefore the best choice is (2) Soil degradation, corresponding to option b.
