We all like to have a good time at the beaches. But that shouldn’t be at the expense of marine life and the health of the oceans, which are already under threat from rising sea temperatures caused by climate change.
Studies have shown that some ingredients commonly found in chemical sunscreens – notably oxybenzone and octinoxate – can cause corals to bleach and die. Having these chemicals in sea water also enable viruses to thrive, while nano particles in the sunscreens could be ingested by corals and other sea creatures.
That is why at the start of this year, the US state of Hawaii enacted a ban on the sale of sunscreens that contain oxybenzone and octinoxate to protect its reefs. Some coastal areas and holiday destinations also have similar bans or encourage visitors to use non-chemical sunscreens.
Of course, saving the coral reefs and oceans takes a lot more than just switching your choice of sunscreen, but every little bit helps. Here are some points to consider when shopping for one:
- The absence of oxybenzone and octinoxate on the ingredients list.
- Go for a mineral-based sunscreen that uses zinc oxide and/or titanium dioxide instead. These mineral particles sit on top of the skin and physically block out UV rays instead of absorbing them like chemical sunscreens.
- Make sure the mineral sunscreen’s has a non-nano formula, which means the ingredient particles are not so tiny that they can be ingested by corals.
Look out for “reef-safe” labels on the packaging.
Do be aware, though, that there are no official guidelines as to what can be termed as “reef-safe” or “reef-friendly”, and no governing bodies to enforce rules. So the best way to check is really to look at the ingredients list on the bottle.
