1. Change up your sunscreen.
Sunscreen, it turns out, is killing coral reefs. Who knew? There’s a chemical in most sunscreens called oxybenzone, which is an endocrine disruptor, meaning that it can alter the way that organisms grow. Even small amounts of oxybenzone in the water can kill nearby coral, which is not only bad for the environment, for for local economies.
So what can you do? Simple: change up your sunscreen. There are plenty of sunscreens that don’t contain oxybenzone (available on this list by the Environmental Working Group here) that you can buy that won’t hurt local reefs.
