Organic farming avoids the use of chemical pesticides and manmade fertilizers. Supporters say organic farming is better for the environment than conventional methods. But studies have shown that organic farming generally produces less food per hectare.有机农业避免了使用化学农药和人工化肥。支持者表示,有机农业比传统农业方式更环保。但研究表明,有机农业每公顷产量通常更低。
