Lakes worldwide are facing a slew of health issues that may become chronic

Like humans, lakes are living systems that can suffer from a number of health issues, including circulatory and respiratory problems, infections, nutritional imbalances, and heat-related illnesses. Without treatment, these conditions can become chronic, harming lake ecosystems and those who depend on them. More than 12% of the world's human population, for instance, lives within 3 kilometers of a lake.
