Ballast water from cargo ships has introduced invasive species like the zebra mussel into North American and European lakes, outcompeting native species. Simultaneously, microplastics have been found in the most remote lakes, including Lake Hovsgol in Mongolia. These particles absorb heavy metals and are ingested by zooplankton, entering the food web at its base. According to the passage, what is the primary
The passage typically discusses how freshwater lakes around the world are facing multiple environmental pressures, including climate change, pollution, invasive species, over-extraction of water, and eutrophication. It often highlights case studies like Lake Baikal, the Great Lakes of North America, and Lake Victoria. Ballast water from cargo ships has introduced invasive
Rising temperatures are dramatically affecting lake health. Warmer air increases evaporation rates directly from the water surface [1, 2]. Furthermore, warmer water holds less oxygen, which can cause "dead zones" where fish and other aquatic life cannot survive.
