参考答案: D
本题详细解析:
Cutting down forests and clearing land for agricultural purposes causes a decrease in the intake of carbon dioxide from the atmosphere which is a leading cause of global warming. By using more renewable energy (Choice A), there will be a decrease in the burning of coal and fossil fuels for generating electricity in power stations. Reducing deforestation (Choice B) will enhance the retention of carbon dioxide by trees through photosynthesis. The use of natural fertilizers like compost (Choice C) instead of fertilizers enriched in nitrogen will reduce the release of nitrous oxide which is a greenhouse gas.
