"This is to me something we need to do in this community to protect our economy. What if we don't pass this and three to five years down the road we have no reef," City Commissioner Jimmy Weekley, who sponsored the measure, told the Washington Post.
"It's not the major cause of the loss of our reef, but this is one reason we can do something about," he added. "We can take a step to eliminate those chemicals going into our water."
The chemicals in sunscreens suck the nutrients out of coral life
A 2015 study from the Archives of Environmental Contamination and Toxicology found that two kinds of chemicals commonly found in sunscreen oxybenzone and octinoxate kill coral reefs by leaching out all their nutrients.
"The chemical not only kills the coral, it causes DNA damage in adults and deforms the DNA in coral in the larval stage, making it unlikely they can develop properly," researchers wrote in the 2015 study , which also reported that about14,000 tons of sunscreen lotion make its way into coral reefs around the world each year.
Swimming in the ocean isnt the only way sunscreen spreads to the reefs.
"The most direct evidence we have is from beaches with a large amount of people in the water ," John Fauth, co-author of the study, told The Post when it was published. "But another way is through the wastewater streams. People come inside and step into the shower. People forget it goes somewhere."
Florida is following Hawaii, which banned these chemically-laden sunscreens in May
Florida is not the first state trying to save the reefs by banning certain sunscreen.
"Amazingly, this is a first-in-the-world law ," Hawaiistate Sen. Mike Gabbard told the Honolulu Star Advertiser in May when the bill was first propose. "So, Hawaii is definitely on the cutting edge by banning these dangerous chemicals in sunscreens. When you think about it, our island paradise, surrounded by coral reefs, is the perfect place to set the gold standard for the world to follow. This will make a huge difference in protecting our coral reefs, marine life, and human health."
Some initially criticized the ban, arguing that it might discourage people to wear sunscreen.
" A ban on these sunscreens in Hawaii the state with the highest daily UV index warnings and very high rates of skin cancer and melanoma would be a public health disaster,"Doug Johnson, a dermatologist and spokesman for the Hawaii Dermatology Society, wrote in a column for the Honolulu Civil Beat.
