If you don’t live near the fading banks of the Salton Sea, it’s easy to forget it exists — that is, until the winds pick up. Depending on which way they are blowing, gusts carry tiny, toxic particulates — and sometimes the stench of decaying fish and sulfur dioxide — from the Colorado Desert to Los Angeles, Phoenix, and points beyond. The smell is a reminder of the public health crisis that will occur if more isn’t done — and quickly — to save the sea.
