Here is one observer's unscientific assessment of the death of Hawaii's ocean life:
Up to 14,000 tons of sunscreen enter the world’s reefs annually, according to a 2015 paper published in the journal Archives of Environmental Contamination and Toxicology. Most of it — including products by Aveeno, Banana Boat, Coppertone, Hawaiian Tropic and Neutrogena — contains a chemical called oxybenzone to deflect UV rays.
Even in minute doses, the researchers found, oxybenzone rapidly bleaches coral and slows new growth: A single drop in 4.3 million gallons of water — about six and a half Olympic-size swimming pools — is enough to be deadly.

WOW !!! That's a lot of sunscreen.
Face it - from many perspectives just about everything humanity does is detrimental to life on our planet.
By the way, I NEVER use sunscreen. I do use plastic bottles, but I recycle the empties.
