As Hawaii, Key West and Palau ban harmful sunscreen ingredients, so many more locations will probably follow.
Coral covers just 1% of the ocean bed yet sustains 25% of ocean life. Life which in turn sustains hundreds of millions of people! This is no small thing.
While global warming and the resulting rise in sea temperatures accounts for most of the reef damage, it is estimated that 10% of the damage is attributable to standard sunscreens.
Many resorts hotels which depend on coral reefs to attract guests now also understand the importance of protecting this vital asset and have banned the use of sunscreens that are not bio-degradable.
However bio-degradable is not enough. Many biodegradable sunscreens, although they might dilute and disperse in water, may still contain ingredients that can trigger a fatal virus in live coral which can decimate a reef.
