Experts say healthcare screening is needed for lakes. 

Researchers say a critical health crisis is affecting the world's lakes. This issue, they argue, not only threatens ecological balance but also the well-being of millions of people globally.

Lakes are suffering from health issues strikingly similar to human diseases, including thermal, circulatory, respiratory, nutritional, and metabolic challenges, in addition to infections and pollution. 

A new study has investigated the state of approximately 21 million lakes larger than one hectare worldwide, uncovering disturbing trends of degradation due to human activities and climate change.

“The ramifications of neglecting lake health are profound,” says Professor David Hamilton, Director of Griffith University’s Australian Rivers Institute.

“Without timely intervention and preventative measures, these issues could escalate into chronic conditions, imperilling essential ecosystem services that millions of people rely upon.”

The study noted a particularly alarming rate of lake evaporation, affecting about 115,000 lakes globally, which poses direct risks to over 153 million people living nearby. 

This phenomenon is significantly influenced by increased evaporation rates in regions such as Australia, parts of Africa, and Central Asia, where water loss surpasses replenishment.

In response to these findings, researchers advocate for a holistic approach to lake management, one that incorporates strategies employed in human healthcare. 

This would include early identification of problems, regular health screenings, and comprehensive remediation efforts to manage and possibly reverse damage. 

“Early identification, regular screening, and remediation efforts are crucial to preserving the health of our lakes,” Professor Hamilton says. 

The researchers hope the study's findings will serve as a call to action for improved sewage treatment, climate change mitigation, and the prevention of non-native species introductions alongside reducing chemical pollution. 

Experts say these steps are critical to averting an ecological disaster and ensuring the sustainability of lake ecosystems for future generations.
