The increase in food production owes much to fertilizers and better machinery. Some people think that it has a negative impact on human health and community. To what extent do you agree or disagree?

高分范文

The surge in food production, largely attributed to the use of fertilizers and advanced machinery, has undoubtedly revolutionized agriculture. However, this advancement brings with it significant concerns regarding human health and the well-being of communities. I partially agree with the notion that these innovations have negative implications, as they indeed pose certain health risks, although they also bring substantial benefits.

To begin with, the use of fertilizers is a double-edged sword. On one hand, fertilizers have substantially increased crop yields, ensuring food security for a growing global population. On the other hand, excessive use of chemical fertilizers has been linked to soil degradation and water pollution, leading to detrimental effects on human health. For instance, nitrates from fertilizers can seep into groundwater, posing risks such as methemoglobinemia, a condition that affects the blood's ability to carry oxygen. This demonstrates how reliance on chemical fertilizers can compromise public health.

Similarly, the advent of advanced agricultural machinery has made farming more efficient, reducing manual labor and increasing productivity. However, this mechanization often leads to environmental damage, which indirectly affects community health. The extensive use of heavy machinery contributes to soil compaction, reducing its ability to absorb water and support plant life, which can lead to erosion and loss of arable land. Furthermore, the carbon emissions from fuel-powered machinery contribute to air pollution, a significant health hazard for nearby communities.

Despite these drawbacks, it is essential to recognize that fertilizers and machinery have played a crucial role in mitigating hunger and poverty by boosting food production. The challenge lies in finding a balance between utilizing these technologies and minimizing their adverse effects. Sustainable farming practices, such as precision agriculture and organic fertilizers, offer promising solutions that could mitigate health risks while maintaining high productivity levels.

In conclusion, while fertilizers and machinery have undeniably enhanced food production, they also present potential health risks. Therefore, it is crucial to adopt sustainable practices to ensure that the benefits of increased food production do not come at the expense of human health and community well-being.

食品生产的增加很大程度上归功于化肥和先进机械的使用,这无疑革新了农业。然而,这一进步也带来了对人类健康和社区福祉的重大担忧。对此,我部分同意这些创新具有负面影响,因为它们确实存在一定的健康风险,尽管它们也带来了实质性的好处。

首先,化肥的使用是一把双刃剑。一方面,化肥大大提高了作物产量,确保了全球不断增长人口的粮食安全。另一方面,过度使用化学肥料与土壤退化和水污染有关,导致对人类健康的有害影响。例如,化肥中的硝酸盐可能渗入地下水,带来如高铁血红蛋白症(影响血液携带氧气能力的疾病)等风险。这表明过度依赖化学肥料可能危害公众健康。

同样,先进农业机械的出现使农业更加高效,减少了体力劳动并提高了生产力。然而,这种机械化往往导致环境破坏,间接影响社区健康。大量使用重型机械会导致土壤压实,降低其吸水和支持植物生长的能力,可能导致侵蚀和可耕地的丧失。此外,燃料动力机械的碳排放导致空气污染,这对附近社区来说是一个重大健康危害。

尽管存在这些缺点,但必须承认,化肥和机械在通过增加粮食生产来减轻饥饿和贫困方面起到了关键作用。挑战在于找到利用这些技术和减少其负面影响之间的平衡。可持续农业实践,如精准农业和有机肥料,提供了有前景的解决方案,可以在保持高生产力水平的同时减轻健康风险。

总之,尽管化肥和机械无疑提高了粮食生产,但它们也带来了潜在的健康风险。因此,必须采用可持续做法,以确保增加的粮食生产的益处不会以牺牲人类健康和社区福祉为代价。

语法分析


主语 (Subject): The extensive use of heavy machinery(大量使用重型机械)
谓语 (Verb): contributes(导致)
宾语 (Object): to soil compaction(土壤压实)
现在分词短语 (Present participle phrase): reducing its ability to absorb water and support plant life(降低其吸水和支持植物生长的能力)
定语从句 (Relative clause): which can lead to erosion and loss of arable land(可能导致侵蚀和可耕地的丧失)

这句话的主要结构是 The extensive use of heavy machinery contributes to soil compaction,表示重型机械的大量使用导致土壤压实,后接的 reducing... 是分词短语,进一步详细说明了压实的后果,最后的 which 引导定语从句,具体描述了最终可能导致的结果。
