A Stinking Problem from a Vanished Sea
The Aral Sea, once a vast inland lake, has been shrinking for six decades. Now, new research indicates its dry seabed is releasing huge amounts of carbon. This environmental crisis highlights the long-term consequences of water mismanagement. The pungent smell from drying lakebeds hints at these gas emissions.

Such emissions are common in many drying lakebeds worldwide. However, the Aral Sea's scale makes its emissions particularly concerning.
Can the Aral Sea Be Saved?
The Aral Sea began shrinking in the 1960s. Rivers feeding it were diverted for irrigation projects. This transformed a thriving ecosystem into a vast, arid wasteland. The exposed seabed now covers an area larger than many countries.
# What caused the Aral Sea to dry up?
Scientists suggest that only a massive flood could reverse the damage. This would re-submerge the exposed sediments. Such an event would trap the carbon and other gases once more. Without it, the emissions will likely continue for decades.
The ongoing carbon release contributes to climate change. It also impacts local air quality and human health. Dust storms from the dry bed carry pollutants far and wide. The environmental and health costs are substantial.
# What are the main gases being released from the dry seabed?
The Aral Sea dried up primarily because rivers feeding it were diverted for agricultural irrigation. This drastically reduced the water flowing into the lake, leading to its rapid shrinkage.
# What is the long-term impact of these emissions?
The main gases released from the dry seabed include hydrogen sulfide, ammonia, and phosphine. These gases contribute to unpleasant odors and environmental concerns.
The long-term impact includes contributions to global warming due to carbon emissions and local air pollution. Dust storms carrying these pollutants also pose health risks to nearby communities.
