What are some of the problems caused by chemical fertilizers？First，they damage the land by killing the helpful bacteria(细菌) and pests(害虫) as well as the harmful ones.Chemicals also stay in the ground and underground water for a long time.This affects crops and，therefore，animals and humans，since chemicals get inside the crops and cannot just be washed off.These chemicals in the food supply build up in people's bodies over time.Many of these chemicals can lead to cancer or other illnesses.In addition，fruit，vegetables and other food grown with chemical fertilizers⑤usually grow too fast to be full of much nutrition(营养)．They may look beautiful，but inside there is usually more water than vitamins and minerals.化肥带来的问题有哪些呢？首先，化肥在杀死病菌和害虫的同时也会杀死有益的细菌和昆虫，从而破坏土地。
