What environmental challenges does the Salton Sea face?

The Salton Sea faces significant environmental challenges, particularly concerning shrinking water levels and air quality issues. Over the years, the Salton Sea has seen dramatic reductions in its water volume due to several factors, such as reduced agricultural runoff, which is its primary source of inflow. This shrinkage has led to an increase in salinity, making it increasingly inhospitable for fish and bird species that rely on the ecosystem.

Additionally, as the water levels recede, toxic pollutants—like heavy metals and agricultural pesticides—concentrate in the exposed lakebed. When these particles become airborne due to wind, they can severely degrade air quality in surrounding communities, posing health risks to residents. This combination of ecological deterioration and public health concerns highlights the gravity of the environmental challenges faced by the Salton Sea.

The other options do not accurately represent the current conditions or challenges confronting the Salton Sea. Increased biodiversity and habitat restoration are not realities in this case; rather, the ecosystem is suffering. Rapid urban development and tourism growth are not significant factors impacting the Salton Sea relative to the pressing issues of water levels and air quality. Additionally, excessive rainfall and flooding are not characteristic of the region's climate challenges, which are often more associated with prolonged drought conditions
