Final answer:
Population growth is a significant factor in the environmental crisis as it leads to overexploitation of resources, habitat destruction, and disruption of ecosystems. It also contributes to global warming and pollution.
Step-by-step explanation:
Population growth is an important force in the environmental crisis because as the human population increases, more resources are required to meet the needs of the growing population. This leads to overexploitation of natural resources, such as deforestation, depletion of freshwater supplies, and the degradation of agricultural soils. Increased population also contributes to global warming and pollution, as more people consume energy and generate waste. These factors have severe consequences for the environment, including habitat destruction, species extinction, and the disruption of ecosystems.
