Planning a holiday to Palau? Take the right sunscreen or you'll be up for a hefty fine.

The Pacific island nation, an archipelago made up of over 500 islands and home to some of the most stunning coral reefs in the world, will become the very first country in the world to ban sunscreens that are harmful to reefs, BBC reports.

It's a whole country ban similar to that imposed by Hawaii, which became the first US state to ban sunscreens deemed harmful to reefs in May.

Like Hawaii, Palau's ban comes into effect in 2020.

Palau's government has reportedly signed legislation that restricts the sale of sunscreen products that contain particular chemicals considered harmful to reefs. Anyone caught with these products is looking at a sizeable $1,000 fine.

So, what chemicals are we looking at? Hawaii's legislature, for one, focuses on the environmental impacts of two chemicals found in some sunscreens, oxybenzone and octinoxate, and their effect on marine ecosystems — including reefs.

According to another report by the BBC, these two chemicals alone are used in over 3,500 popular sunscreen products worldwide.

Say, haven't we already heard about these chemicals?

As we've noted before, the effects of one of the banned chemicals, oxybenzone, on coral reefs proved the cornerstone of a scientific study released in 2015, which sparked global headlines faulting sunscreen for the decline of reefs.

The study, published in the journal, Archives of Environmental Contamination and Toxicology, determined the chemical had a detrimental effect on the DNA of coral. 

But many scientists criticised the controlled laboratory conditions of the experiments, and argued that although the chemicals do have a negative effect on the reefs, in the scale of things they have much more serious threats than sunscreen toxins — we're talking ocean acidification and coral bleaching caused by human-induced climate change, and pesticide/waste run-off.

According to the recent (and rather damning) UN report on climate change, a feared 2 degrees Celsius jump in global average temperatures means some 99 percent of corals will disappear from the planet completely. Even if it rises by 1.5 degrees Celsius, a 70 percent global loss is predicted.

So, a country-wide ban on chemicals impacting coral reefs is great news, there's no doubt about that, but perhaps legislation that adequately tackles climate change is as pressing a need.
