Green Screen: Saving Your Skin—And The Reefs

Sunscreen may spare your skin, but when it inevitably rinses off in the waves, it’s an eco-nightmare. Up to 6,000 tons of the goop end up in oceans every year, according to a 2007 Italian university study, and the chemicals are bleaching coral reefs at an alarming rate. Two Mexican marine parks have banned traditional sunscreens, and more are sure to follow suit. Aubrey Organics Natural Sun is a bit pricey ($8.50 for four ounces) but delivers where it counts: It protects your skin from rays as well as other screens—and saves reefs from a total wipeout. Plus, using it will make you smell like a White Russian.
