Oceans Acidifying Fast
The world’s oceans are becoming more acidic due to rising atmospheric CO₂, threatening marine life and ecosystems.

 

Geoengineering Ideas
Researchers are exploring ways to raise ocean pH—like adding alkaline minerals or “antacids”—to counter acidification and help the seas absorb carbon.

 

Controversy and Limits
Such interventions are experimental, controversial, and may have unknown ecological impacts; reducing emissions remains crucial.
