Earth Lakes Are Under Threat Reading Answers

Once the fourth-largest lake in the world, it began to shrink in the 1960s after rivers were diverted for irrigation, primarily for crops like . Now, the exposed lake bed releases salt that wind carries across a 300-kilometer radius, damaging surrounding agriculture. Changing Chemistry and Ecosystems

Rising global temperatures are the principal culprit. Warmer air increases evaporation rates, especially in arid and semi-arid regions. Simultaneously, many lakes rely on glacial meltwater; as glaciers retreat, these lakes experience a “peak water” phenomenon, after which inflows decline permanently. For example, Lake Powell in the southwestern United States has reached historically low levels, while Bolivia’s Lake Poopó has virtually disappeared. Climate models predict that for every 1°C of warming, lake evaporation increases by 3–5%, exacerbating water loss. Once the fourth-largest lake in the world, it
