CORAL REEFS vs SUNSCREEN:  A chemical called oxybenzone which is found in sunscreen and other personal care products is decimating coral reefs, making coral more susceptible to bleaching.  Nearly half of Hawaii's coral reefs were bleached during heat waves in 2014 and 2015.  Any small effort to reduce oxybenzone pollution could mean that a coral reef survives a long, hot summer, or that a degraded area recovers.  While there are a lot of things we can’t do anything about, this is one thing we can do right now for the environment.
