Once Bolivia’s second-largest lake, it has essentially vanished. A lethal combination of global warming, persistent drought, and upstream irrigation projects has turned a thriving fishing hub into a salt-crusted desert. The Aral Sea (Central Asia):

Chemical fertilizers used in farming contain high amounts of phosphorus and nitrogen. Rainwater washes these nutrients into nearby lakes, triggering massive algal blooms. This process, called eutrophication, blocks sunlight and depletes dissolved oxygen when the algae die and decompose. The result is massive fish kills and toxic water conditions.

Lakes are hotspots of biodiversity. When they dry up or become too salty/polluted, unique species—many of which are found nowhere else—face extinction. Key Themes in Academic Reading Passages Lakes are

One of the primary drivers of lake depletion is the over-extraction of water for agriculture and industry. The Aral Sea serves as a tragic case study; once the world’s fourth-largest lake, it began to shrink in the 1960s after its feeder rivers were diverted to irrigate desert crops like cotton and rice. The resulting disappearance of the water has exposed vast salt flats that create toxic dust storms, damaging surrounding soil and health for hundreds of kilometres. Similarly, Lake Poopó in Bolivia has essentially vanished, leaving fishing communities without food or income. " or "dammed."
