Last week our class held a discussion about organic farming and chemical farming.As far as I’m concerned，organic farming is preferable to chemical farming.Here are some reasons. Firstly，organic farming produces tasty food that is rich in nutrition because of not using artificial fertilizers.In addition，organic farmers use animal waste as natural fertilizer，which is good for improving the condition of the soil.Meanwhile，the environment is protected from chemical pollution.By contrast，chemical farming can cause damage/harm to water，soil and ecosystems.So，in the long term，the benefits of organic farming exceed those of chemical farming. To conclude，in my opinion，it is organic farming that farmers should choose.I do hope more and more farmers will turn to organic farming in the future. 返 回 本课结束 $
