UGC NET Questions (Paper – 1)

Population explosion describes a very rapid and often uncontrolled rise in population. Such growth can intensify pressure on land,water and other resources. It frequently contributes to deforestation,pollution and environmental degradation. Therefore the situation presented in the question is best captured by the term population explosion.

Option A:
Population explosion directly implies that population size is increasing faster than the capacity of the environment and infrastructure to support it. This mismatch leads to overuse of resources and ecological stress. Hence it appropriately summarises the phenomena listed in the stem.

Option B:
Demographic transition refers to a long term shift from high to low birth and death rates. It is a model of population change over time,not specifically a description of rapid overuse of resources. Thus it is not the most accurate answer here.

Option C:
The Green revolution relates to the introduction of high yielding varieties,irrigation and fertilisers to increase agricultural production. Although it had environmental consequences,it is not a term for rapid population growth. Therefore it does not fit the question’s description.

Option D:
Urban renewal is a process of redeveloping deteriorated urban areas. It may change population distribution but is not a synonym for rapid population increase. Hence it is not appropriate for the stem.
