What happens if the Salton Sea dries up?
The climate in the area will shift, making winter more difficult for farmers in the area. The birds will have no place to rest along their migratory routes. However, most worrisome of all is the impact the drying sea can have on human health.
First, let’s imagine the scale of the Salton Sea. It is visible from orbit, shaped like a footprint in the sand, spread out over 343 square miles (889 km2). That is almost the size of Hong Kong and big enough to fit Manhattan Island ten times over. Now imagine that it has become a dry lakebed with very fine soil, perfect for being carried on the high winds common in the area. In the desert of Southern California, a sea of sand and gravel, more dusty space doesn’t seem like much of a concern. The major difference lies in the makeup of the dust and the sand. In the desert, the sand is made of silica and calcium carbonate, having the potential to clog up the lungs and irritate mucous membranes. In short, normal sand might give you a bad cough, but little else. In the case of the Salton Sea, dust can turn into a more serious health hazard.
