Conclusion: Although organic farming cannot meet global food demand now, it is the sustainable future of agriculture. 三、参考范文 Organic Farming Is a Better Choice In my opinion, organic farming is preferable to chemical farming because it guarantees sustainable agriculture and people’s long-term health. Chemical farming relying on pesticides and fertilisers can increase crop output quickly. However, its long-term use damages soil ecology, kills beneficial creatures and leaves harmful chemicals in food, which may cause diseases.By contrast, organic farming uses natural methods to grow crops. It protects soil, water and air from pollution and produces more nutritious and tasty food. Although it costs more and cannot satisfy global food demand at present, it brings no hidden dangers to the environment and human health. From my point of view, organic farming is the future of green agriculture. We should promote it steadily for sustainable development. 5.

Chemical farming can raise crop output quickly to meet global food needs. However, long-term use of chemicals damages soil quality, pollutes water sources and threatens human health. In my eyes, it is a short-sighted farming method. Without a doubt, organic farming is more sustainable. It uses natural resources to protect soil ecology and produce safe, nutritious food. Though it has limitations in output at present, it is the best choice for long-term agricultural development. I believe green organic farming will create a better future for mankind. 14 / 17 学科网（北京）股份有限公司 学科网（北京）股份有限公司 $
