假如你是高一学生李华，在学习了本单元话题内容后了解到使用化肥的“利与弊”。为了呼吁大家保护环境，请你根据以下表格提示，用英语写一篇文章。第一步，认真审题。
介绍使用化肥的“利与弊”，时态方面应该用一般现在时。
第二步，信息重组。
内容中使用化肥的“利”可作为一句；“弊”有三点，可以分别用一句表达；最后“个人看法”再用一句表达。写作过程第三步，翻译句子。
每组句子用一个英语句子来表达，若基础一般，建议先用五个完整的汉语句子表达出来，然后再将这五个句子译成英语。如：
1. 尽管化肥带来了很多好处，例如使作物生长的更快，为农民节省时间，但是使用它们所带来的消极方面也不容忽略。
2. 首先，化肥会杀死有益的细菌和昆虫，破坏土壤。3. 而且，施肥过多会导致水污染，破坏生态环境。
4. 长期使用化肥会影响人们的健康。
5. 就我个人而言，我认为农民应少使用化肥，而尽量使用有机化肥。
第四步，连句成文。
必要时可适当添加起衔接作用的关联词。 Over the past half century, using chemical fertilizers has become very common in farming. Although chemical fertilizers have brought a lot of benefits, like making the plants grow much faster and save our farmers time and energy, the negative aspects of using them can’t be ignored. To begin with, chemical fertilizers can damage the soil by killing the helpful bacteria and insects. What’s more, using too many chemical fertilizers can lead to water pollution or, even worse, can spoil the ecological environment. And long-term use of them can even have a bad effect on people’s health. From my point of view, farmers should use more organic fertilizers rather than chemical fertilizers.
