Answer:
D. Large and rapidly growing population is the correct answer.
Explanation:
As population grows more food is needed. The measures are intensive farming and creating more land through deforestation. The output is increased by using pesticides, fertilisers and mechanisation and all these lead to soil erosion and depletion. Deforestation leads to reduction in the ability to capture carbon dioxide and to loss of habitats and extinctions. Agriculture is responsible for eighty percent of deforestation and if the increase in human pressure leads to deforestation. More people means more foods and the pressure of food production leads to deforestation and land degradation. Population affects food supply-demand balance. Sustainable development can help with all these issues.
