Ecological footprint interpretation – UGC NET Question

The ecological footprint measures how much biologically productive land and water area is needed to supply a population’s resources and absorb its wastes. High consumption of meat, energy-intensive goods and frequent air travel significantly increases this demand. Meat production requires large amounts of land, water and feed, while energy-intensive products and aviation burn substantial fossil fuels. Thus, a rapid rise in such consumption patterns increases the ecological footprint more than efficiency improvements or afforestation.

Option A:
Option A would generally reduce ecological footprint because mass public transport uses energy more efficiently per passenger than private cars. It lowers fuel consumption and associated land use for roads and parking.

Option B:
Option B is incorrect as afforestation and forest protection expand biocapacity rather than demand. They can help balance or even reduce the ecological deficit by increasing nature’s ability to regenerate resources and absorb carbon.

Option C:
Option C is incorrect because improving energy efficiency reduces the energy needed for the same level of output or comfort. This typically lowers resource use and emissions, thereby shrinking the ecological footprint if rebound effects are controlled.

Option D:
Option D is correct since increased meat consumption, energy-hungry lifestyles and air travel are well-known drivers of higher footprints in affluent societies. These behaviours raise per capita resource demand and waste generation beyond what local or global ecosystems can sustainably supply.
