The world’s ocean covers nearly three-quarters of the planet, but there has never been a comprehensive international treaty to protect its biodiversity.

After large rainstorms, runoff from the land containing contaminants from cars, trucks, farms, ranches, septic tanks, and sewage is one of the largest sources of ocean pollution. Sometimes, beaches are closed because of E.coli and other bacteria from waste in the water, but now there are concerns that pollutants can become airborne in sea spray and reach people a mile or two inland—far beyond surfers, swimmers, and other beachgoers.

Spring is right around the corner, and soon we can look forward to some of our favorite seasonal fruits and vegetables, like juicy strawberries. But a new study says, buyer beware.
