Desalination Expands Amid Droughts, Raises Environmental Concerns

4/1/2026

Summary

Story summary

Desalination, mainly via reverse osmosis, is increasingly used to produce freshwater as droughts worsen, supplying hundreds of millions globally.
The process generates significant carbon emissions and brine that can harm marine ecosystems, while mitigation includes renewable energy use and improved technology.
Experts advocate prioritizing water recycling and conservation, which are more energy-efficient and less harmful to marine life, noting desalination growth in the United States and the Middle East.
