This essay draws on key themes from the passage "Earth’s Lakes Are Under Threat," which highlights the environmental challenges facing vital freshwater bodies like Lake Poopó, the Aral Sea, and Lake Tanganyika.

Answer: NOT GIVEN

Lakes hold over 80% of the world’s liquid surface freshwater. They support critical ecosystems, provide drinking water, and regulate local climates. However, recent environmental studies reveal a troubling reality: more than half of the world's large lakes are drying up.

Compounding the effects of climate change is the relentless influx of pollutants. Agricultural runoff, rich in nitrogen and phosphorus from fertilisers, enters lakes via rivers and streams. This nutrient overload fuels eutrophication—the explosive growth of harmful algal blooms (HABs). These blooms can be toxic to humans and animals, block sunlight, and create vast oxygen-depleted zones. Lake Okeechobee in Florida and Lake Taihu in China regularly experience such blooms, forcing municipal water plants to shut down and decimating local fisheries. Industrial discharge and untreated sewage add heavy metals and pathogens, making water unsafe for consumption and recreation. Unlike climate change, which requires global cooperation, pollution is a local insult that can be mitigated with stricter regulations and better farming practices.
