The question is directly answered from the "Development of Resources" section, which lists the problems caused by indiscriminate resource use. For 2 marks, mention two or three distinct adverse effects — examiners look for global ecological crises (global warming, ozone depletion, pollution) and land degradation as the key points. Avoid vague answers; use the textbook's exact terminology like "global ecological crises" and "land degradation."
