In an attempt to protect the coral reefs, which divers so admire they have dubbed them the underwater Serengeti, the Pacific nation of Palau will soon ban many types of sunscreen.
President Tommy Remengesau Jr has signed legislation that bans "reef-toxic" sunscreen from 2020. Banned sunscreens will be confiscated from tourists who carry them into the country, and merchants selling the banned products will be fined up to $1395.
Mr Remengesau said in a statement the penalties found the right balance between "educating tourists and scaring them away".
The law defines reef-toxic sunscreen as containing any one of 10 chemicals, including oxybenzone, and states that other chemicals may also be banned. The legislation also requires tour operators to start providing customers with reusable cups, straws and food containers.
