Ten Reasons to Get Travel Insurance For Your Next Trip

Some of the pollutants slowly trickling into the oceans are the chemicals in many sunscreens. As swimmers jump into the sea, their sunscreen washes away and filters into the water. Scientists who have become aware of the dangerous effect these chemicals have on coral reefs have developed the best reef-safe sunscreen brands to protect you and the ever-important marine life that inhabits our oceans. Knowing coral reef safe sunscreen information will help keep the sea beautiful and alive.

“Eighty-five percent of the Caribbean coral reefs died before 1999 or 2000. That wasn’t global warming. It’s pollution,” says Dr. Craig A. Downs, Ph.D., executive director of Haereticus Environmental Laboratory.

Making an eco-savvy choice, therefore, and using reef-safe sunscreen matter. And not only for the corals.

Dr. Downs and his group began taking a gander at particular synthetic concoctions and found that oxybenzone and octinoxate are the principle guilty parties. The reason they are so generally utilized in sunscreen is that they assimilate the unsafe UV beams. For humans, oxybenzone and octinoxate are chemical sunscreen ingredients that keep harmful UV rays from penetrating the skin, killing cells, and causing a burn. However, they have the opposite effect on coral reefs. These reefs, which are generally bright colors, end up bleaching to bone white under the harsh rays of the sun when they come into contact with these chemicals.

Oxybenzone, for example, is toxic in four different ways: it causes damage to the DNA that may lead to cancer and developmental abnormalities, it is an endocrine disruptor, it causes deformations in juvenile corals, and, lastly, it leads to bleaching.

Dr. Downs points out that certain preservatives found in sunscreens are also toxic: parabens such as the commonly used methyl paraben and butyl paraben, or phenoxyethanol

Another safe alternative to oxybenzone and octinoxate is non-nano titanium dioxide. Before purchasing your next bottle of sunscreen, also check the list of for any of the toxic preservatives we mentioned.
Hawaii is planning on banning certain sunscreens in 2021 that contain harmful compounds.
In addition to oxybenzone and octinoxate, read the label on your sunscreen to see if it contains any of these other destructive chemicals: homosalate, octisalate, octocrylene, avobenzone, dimethicone, parabens, BHT, nanoparticles, propylene glycol, and retinyl palmitate.

Here are five reasons why your choice of sunscreen matters.

1. Chemical Sunscreen Can Awaken Coral Viruses

Sunscreens washed off into the ocean each year change the chemical composition of the water and make it a thriving place for viruses and bacteria. Some of these viruses attack corals, causing them to expel their life-giving algae, a situation that causes coral bleaching and the viruses spread to the surrounding coral communities.

2. Chemical Sunscreen Ingredients Can Bleach or Kill Corals

Besides viruses, research has also shown that some ingredients in chemical sunscreens can cause coral bleaching and potentially kill these organisms.

While most countries implementing sunscreen bans fight against oxybenzone and octinoxate alone, scientists have identified that butylparaben and 4-methylbenzylidene camphor can also have a similar action.

Using a sunscreen free of these ingredients is essential if we want to preserve the integrity of the marine ecosystem.

3. Chemical Sunscreen Can Harm More Than Corals

The compounds that cause coral bleaching can also affect other forms of marine life. Fish are also affected by oxybenzone and octinoxate.

Here is one example from Dr. Downs, who was on a working visit at the Bahamas, he was conversing with an administration worker at supper who shared how much he loved the coconut kind of the neighborhood angle they were eating on.

“We solicited the gourmet expert what kind from flavoring he put in it, and he stated, ‘simply salt.’ The coconut was some recombinant aroma of sunscreen. That is a substance aroma. It’s a terrible, dependable scent that will amass in life forms thus we were tasting it in the fish,” Dr. Downs explained.

So what can you do next time you hit the beach to prevent further damage? First of all, forget about aerosols.

These substances act as hormone disruptors and induce feminization in male fish. This leads to the interruption of their sexual activity, affecting the reproduction of many species

4. Sunscreen Pollution Threatens Local Economies

The death of coral reefs leaves many species of fish and crustaceans without a habitat; a situation that leads to the death of this marine wildlife. Combined with the affected fish reproduction, chemical sunscreens contribute to the extinction of many fish species.

This has two important consequences: famous diving spots become sterile and unattractive and less fishing possibilities for local businesses who base their subsistence on fishing.

5. Chemical Sunscreens Affect Humans Too

Chemicals in sunscreen are not only bad for the environment. They are bad for humans too. Besides rashes and allergic reactions, researchers also investigate the carcinogenic effects of both oxybenzone and octinoxate.
Other chemicals typically used in these products also act as hormone disruptors and can affect both fetuses if used by pregnant women as well as infants and toddlers.

Considering the negative impact chemical sunscreens have on both us and the environment, changing our habits and using an eco-friendly approach matters.
