The Salton Sea in California is considered the worst environmental disaster in California's History. The Salton Sea is California's largest lake and has been shrinking for years. Fish and birds have been dying. The dry lake bottom already spews toxic dust into the air, threatening a region with hundreds of thousands of people. For more than a century, the lake has been sustained by water from the Colorado river. Now this water flow will be cut dramatically, causing the lake to shrink faster than ever before and sending more toxic dust blowing through low-income, largely Latino farming communities. The ecosystem is starting to collapse. The lake is already saltier than the ocean, and the remaining fish will soon die out as the salinity rises.
