海水污染英语作文120词
英文回答：
Marine pollution, a pervasive and insidious threat to our oceans, poses grave consequences for marine ecosystems and human health. Industrial activities, agricultural runoff, sewage discharge, and plastic waste all contribute to the degradation of our oceans.
Chemical pollutants, such as heavy metals and pesticides, accumulate in marine organisms, disrupting
their physiological processes and posing a risk to consumers. Oil spills, caused by accidents or deliberate discharges, can have devastating effects on marine life, contaminating habitats and harming wildlife.
Nutrient pollution, primarily from agricultural runoff, leads to eutrophication, a condition where excess nutrients cause algal blooms. These blooms can deplete oxygen levels, suffocating marine life and creating dead zones where
aquatic organisms cannot survive.
Plastic pollution is perhaps the most visible and widespread form of marine pollution. Plastic debris entangles marine animals, harms their digestive systems,
and accumulates in the food chain. Microplastics, tiny pieces of plastic, are even being found in marine organisms at the base of the food chain.
Marine pollution poses significant risks to human health. Consumption of contaminated seafood can lead to poisoning and health issues. Harmful algal blooms can produce toxins that threaten the health of shellfish consumers and those who swim in polluted waters.
Addressing marine pollution requires a comprehensive approach involving governments, industries, and individuals. Reducing industrial emissions, improving agricultural practices, and implementing effective waste management systems are crucial steps towards mitigating this problem.

海水污染。

海水污染是对我们海洋的一种普遍且隐蔽的威胁，对海洋生态系统和人类健康构成严重后果。

工业活动、农业径流、污水排放和塑料废物都加剧了海洋的恶化。

重金属和杀虫剂等化学污染物在海洋生物体中积累，破坏它们的生理过程并对消费者构成风险。

由事故或故意排放造成的石油泄漏会对海洋生物造成毁灭性影响，污染栖息地并伤害野生动物。

营养污染，主要来自农业径流，会导致富营养化，这是一种因过量营养物质导致藻类大量繁殖的病症。

这些藻类大量繁殖会消耗氧气，使海洋生物窒息，并形成水生生物无法生存的死亡区域。

塑料污染可能是最明显且最广泛的海水污染形式。

塑料碎片缠绕海洋动物，损害它们的消化系统，并在食物链中积累。

微塑料，微小的塑料碎片，甚至被发现存在于食物链底端的海洋生物中。

海水污染对人类健康构成重大风险。

食用受污染的海鲜会导致中毒和健康问题。

有害藻华会产生毒素，威胁食用贝类者的健康以及在受污染水域游泳者的健康。

解决海水污染需要政府、行业和个人采取综合方法。

减少工业排放、改善农业实践和实施有效的废物管理系统是缓解这一问题至关重要的步骤。
