Beyond losing water quantity, lakes are losing quality. Agricultural runoff containing fertilizers causes eutrophication—a process where nutrient oversupply causes algae blooms that consume oxygen, creating "dead zones" where fish and other aquatic life cannot survive. 3. The Consequences: A World Without Lakes
Addressing these threats requires a combination of local action and international cooperation. Complete the sentences below
To master reading passages on environmental science, you must recognize these high-level contextual terms:
: v (The compounding impact of rising temperatures) are all responsible for its disappearance
Crucially, the threat extends beyond simple volume loss. Water quality is deteriorating at an accelerating rate. As water levels drop, the concentration of pollutants, agricultural runoff, and industrial waste spikes dramatically. Higher water temperatures also trigger massive algal blooms. These blooms consume dissolved oxygen, creating vast "dead zones" where fish and other aquatic organisms cannot survive. Toxic cyanobacteria from these blooms pose direct health risks to human populations relying on these reservoirs for drinking water.
