An invasive species that escaped into America's waterways is now reshaping entire freshwater ecosystems — and threatening the Great Lakes.一种逃入美国水域的入侵物种，正在重塑整个淡水生态系统，并威胁着五大湖。
Asian carp are invasive fish originally from Asia. They were introduced into the United States in the 1970s to help control algae and aquatic weeds in aquaculture systems.
亚洲鲤鱼是原产于亚洲的入侵性鱼类。它们于上世纪 70 年代被引入美国，用于帮助控制水产养殖系统中的藻类和水草。
However, due to flooding and rapid reproduction, they escaped into natural waterways and spread throughout the Mississippi River and Illinois River basins — multiplying far beyond control.
然而，由于洪水泛滥与惊人的繁殖速度，它们逃入自然水域，蔓延至密西西比河与伊利诺伊河流域，数量远超可控范围。
Asian carp consume large amounts of plankton and aquatic organisms — up to a significant portion of their body weight every day.亚洲鲤鱼每天吞食大量浮游生物与水生生物，摄食量可达自身体重的相当比例。
They outcompete native fish for food and habitat.在食物与栖息地上挤压本土鱼类。
Stripping plankton disrupts the entire aquatic web.大量摄食浮游生物，扰乱整个水生生态网。
Freshwater ecosystems lose biodiversity and resilience.淡水生态系统的生物多样性与韧性下降。
Tens of millions rely on the Great Lakes for water and fisheries.数千万人依赖五大湖的饮用水与渔业。
Although electric barriers and government measures have been used in some waterways, these efforts have not fully stopped the northward spread of Asian carp.
尽管部分水域已部署电屏障并采取了政府措施，但这些努力仍未能完全阻止亚洲鲤鱼向北扩散。
A lasting solution requires a coordinated, science-driven strategy — combining population control, ecological research, sustainable utilization, and long-term monitoring.
持久的解决之道需要协调一致、以科学为驱动的战略——将种群控制、生态研究、可持续利用与长期监测相结合。
With sustained investment and collaboration, we can turn the tide for America's freshwater.凭借持续投入与广泛合作，我们能够扭转美国淡水生态的局势。
