大量塑料垃圾(巨型塑料)向海洋泄漏是一个主要的环境问题。其中很大一部分泄漏来自沿海城市，特别是在极端降雨事件期间。随着沿海城市的持续发展，找到减少这种巨型塑料泄漏的方法是非常有意义的。在这里，我们探索为什么以及如何沿海城市可以减少极端降雨事件中的大型塑料泄漏。以9个全球城市为基础，我们发现，尽管城市积极制定减少塑料泄漏的政策，但还需要做更多的工作。尽管如此，这些政策对城市环境在经济、社会和环境方面都是有益的。虽然缺乏政治参与和经济关切限制了这些政策，但缺乏社会动力和参与是执行政策的最大限制。我们建议城市鼓励公民和市政当局负责任地使用塑料，清洁环境，并为未来的极端降雨事件做好准备。
The leakage of large plastic litter (macroplastics) into the ocean is a major environmental problem. A significant fraction of this leakage originates from coastal cities, particularly during extreme rainfall events. As coastal cities continue to grow, finding ways to reduce this macroplastic leakage is extremely pertinent. Here, we explore why and how coastal cities can reduce macroplastic leakages during extreme rainfall events. Using nine global cities as a basis, we establish that while cities actively create policies that reduce plastic leakages, more needs to be done. Nonetheless, these policies are economically, socially and environmentally cobeneficial to the city environment. While the lack of political engagement and economic concerns limit these policies, lacking social motivation and engagement is the largest limitation towards implementing policy. We recommend cities to incentivize citizen and municipal engagement with responsible usage of plastics, cleaning the environment and preparing for future extreme rainfall events.
