What does daily sunscreen have to do with corals in the sea?

Summer is coming, sunscreen is becoming more and more common in daily life, regardless of men, women and children, in order to resist the attack of ultraviolet rays, they have to apply sunscreen for themselves when they go out to protect**. All kinds of sunscreen propaganda are endless, and some news has said that if you want to whiten, the first step is sunscreen, even if it is cloudy, you should use sunscreen. However, have you ever thought that sunscreen does not only affect humans, because some sunscreen ingredients in sunscreen will also make some species on the earth slowly disappear?

Corals in the sea are a prime example of sunscreen. Coral reefs, known as the "marine tropical forests", are one of the most complex and important ecosystems in the marine ecosystem. It is important to know that there are currently about 30 million people in the world who are completely dependent on coral reefs for their survival, and about 500 million people rely on coral reefs for food to varying degrees.

However, studies have shown that between 6 and 14,000 tonnes of sunscreen are washed and entered into coral reef areas each year, and the two chemicals contained in sunscreen products: ethylhexyl methoxycinnamate and benzophenone-3 are extremely threatening to coral survival. These sunscreen factors are able to cause coral reefs to bleaching by absorbing ultraviolet rays.

The most severe impact on corals is benzophenone-3, which prevents the growth of baby corals and has been shown to be toxic to many different coral species in laboratory tests. It causes corals to bleach at lower temperatures and reduces their resilience to climate change. It is important to know that the resilience of coral reefs to climate change has a direct impact on their survival and reproduction.

So far, in order to protect fragile corals from the chemicals in these sunscreen products, a number of regions have imposed bans on sunscreens containing ethylhexyl methoxycinnamate and benzophenone-3 chemicals. Even Palau, located on the west coast of the Pacific Ocean, has banned the use of sunscreen to protect the country's fragile coral reefs, and Mexico has banned the use of sunscreen in nature reserves. At the same time, we should also contribute to the environment as much as we can through our own actions, such as minimizing the use of sunscreen and switching to physical sunscreen; If you want to use sunscreen, try to choose a sunscreen that is mainly physical sunscreen, etc.

You know, to protect the environment is to protect ourselves.

The sunscreen we use every day, after washing, the water directly or indirectly enters the sea, and the substances in it will be bad for the coral, and the most serious thing is that the coral will die in large quantities.

According to the survey, the daily use of sunscreen can be extremely harmful to the corals in the sea, and this harm is huge.

Sunscreen has an effect on corals, mainly because sunscreens contain chemicals that can break down corals, causing them to lose a lot of nutrients and eventually die. You can think about how many people play on the beach every year, and these people who play on the beach will eventually choose to swim in the sea or something, these people will apply sunscreen on their bodies to avoid getting tanned, and the sunscreen eventually goes to the sea, so think about it carefully, there will be a large number of corals planted on the hands of sunscreen every year.

In fact, I personally think that these sunscreens can be so harmful to corals, and what kind of damage will people do when using sunscreens for a long time, so it is still necessary to be restrained when using sunscreenDon't often apply a lot of sunscreen on your body, long-term use of sunscreen in large quantities will cause our own pores to clog, and even breed some blackheads and other things, and the chemicals in it may also have a certain risk of causing cancer.

In fact, without wearing sunscreen, we can also do our own sunscreen work very well, such as playing on the beach, and when basking in the sun on the beach, we can wear a sunscreen clothingIf you want to swim in the sea, you can take off the sunscreen clothing, and continue to put the sunscreen clothing on when you come back from swimming, so that the sun can't shine on you, including going out to play in the summer.

Sunscreen contains oxybenzone and octyl methoxycinnamate, both of which can hinder the growth of coral larvae and may cause coral bleaching.

The first is that corals are extremely sensitive to the chemicals in sunscreens, and most sunscreens contain chemicals that are highly toxic to corals, so they can have a great impact on corals.

Sunscreens contain things like zinc and titanium dioxide, where octanate can cause coral bleaching and exposure to oxybenzene can cause small corals to die.

The oxybenzone contained in sunscreen can be converted into phototoxins that can be fatal to corals. Liao Baolin, a coral conservation expert at Guangdong Ocean University, told Purple Cow News on the evening of the 6th that a very small amount of sunscreen can also cause fatal damage to corals and other marine organisms, and the use of sunscreen should be minimized in order to protect the marine environment.

The latest study, conducted by Djordjevuckovic of Stanford University in the United States, found that oxybenzone is a popular sunscreen ingredient that is absorbed into the body by sea anemones and corals and converts it from a UV blocker into a potent phototoxin.

"The discovery that oxybenzone sunscreens can poison sea anemones may suggest that it is also more toxic to albino corals, and that it can actually contribute to global warming," Wackerwiczi said. ”

This is because sunscreens always have special substances that are harmful to corals.

Some ingredients in sunscreen are not good for corals.

It is precisely because of the high requirements of corals for the living environment that their living environment is relatively stable, and once the chemical substances produce bioaccumulation, they will intensify in an area, resulting in the threat of the coral's living environment.

Because there is a substance in sunscreen that is dangerous for corals.

Sunscreen contains special substances that are harmful to corals.

There are chemicals in sunscreen.

It is found in 3,500 brands of sunscreens around the world, including the popular L'Oréal, Banana Boat, Water Baby and Neutrogena.

Corals have high environmental requirements for their living space.

Probably, they are reactions of mutual restraint.

Sunscreens always have special substances that are harmful to corals.

Bioaccumulation of chemicals can intensify in an area, threatening the coral's habitat.

In the variety show "Hello Life", there is an issue where the task is to plant coral, and the host goes to the sea without makeup, in order to protect the coral from being harmed by sunscreen and other cosmetics, what is the harm of sunscreen to coral? I'll introduce you below.

Hello life, why do you ask to plant corals without makeup?

With the continuous expansion of human activities, the increasing forms of activities, and the pollution caused to the environment is also increasing, which has caused a large number of coral deaths, so planting corals has become an extremely meaningful thing.

And we commonly use skin care products, cosmetics, these things, which contain all kinds of chemicals, many will cause damage to coral, increase the mortality of coral, coral protection researchers said that cosmetics is a factor of coral bleaching, therefore, in the planting of coral branches Nian Tan time Mengtong, people must be the elements of the water, do their best to protect coral, without makeup, to go to the sea, in order to protect the marine ecology.

What is the danger of sunscreen to corals.

Sunscreen is harmful to corals This problem was discovered by researchers in the United States as early as 2008, and studies showed that benzophenone (a synthetic compound that acts on various types of cosmetics with sunscreen functions) This ingredient not only causes coral bleaching, but also interferes with the endocrine system of sea-high organisms such as shrimp and clams, thus affecting the entire ecosystem.

And another ingredient: ethylhexyl methoxycinnamate was one of the most commonly used sunscreens in the world at the time, and it was also harmful to corals and marine ecology like benzophenone.

To put it simply, the sunscreen contained in the vast majority of sunscreens on the market will cause such consequences when they flow into the ocean. And his impact is not as simple as "just a little bit of it doesn't matter" as you imagined.

Studies have found that 10% of the world's coral reefs are threatened by harmful substances in sunscreens. In addition, 4,000 to 6,000 tonnes of sunscreen are washed off by water riders every year.

Humanity is constantly improving, and science tells us that if we want to keep you young and healthy, apply sunscreen. So we use a variety of products with peace of mind, and those products are fragrant and pleasant. And just a little sunscreen in the palm of our hand is enough to kill an entire area of coral reefs.

In the last 30 years, corals have died by a full 50%, and at this rate, in 30 years, there will be no corals on the planet.

Coral is an invertebrate that requires a high living environment, but as long as the right environment can create a coral reef ecosystem with high primary productivity.

There are about five main types of coral damage that have been assessed so far:

Climate change, runoff pollution (upstream agricultural pollution, anthropogenic pollution in tourist areas), coastal zone development (indirect effects of destruction of marine ecosystems), direct damage (fishery impacts, ecological changes caused by the killing of upper trophic levels, physical damage caused by fishing and exploding, invasion of alien species).

Sunscreen is very harmful to coral reefs, and these sunscreens can flow into the water through various channels and eventually cause coral reefs to die.

Between 4,000 and 6,000 tonnes of sunscreen enter the reef area each year. But beachgoers aren't alone in spreading these harmful chemicals. Kids on the playground and runners alike go home to wash off the same chemicals that will eventually be washed out into the sea as well.

Just a small amount of sunscreen containing oxybenzone is enough to break down the coral, causing it to lose nutrients and turn white, eventually dying. That's because when you spray sunscreen, a lot of sunscreen falls in sand or water. When the tide comes, the tide washes away all the residue and eventually returns to the sea.

Oxybenzone is a synthetic compound that absorbs ultraviolet rays, so it is used as a member of sunscreens, and it is also found in moisturizers and lipsticks that have sunscreen properties. Octyl p-methoxycinnamate is currently one of the most commonly used sunscreens in the world. Because it also has an excellent ultraviolet absorption curve, and has a high absorption rate, good safety, minimal toxicity, and has good fat solubility.

Therefore,It is found not only in sunscreens, but also in chemical fields such as plastics, rubber, and coatings.

It is precisely because of the high requirements of corals for the living environment that their living environment is relatively stableOnce chemicals bioaccumulate, they can intensify in an area, threatening the coral's habitat.

The chemicals in sunscreen attach to coral reefs through seawater and can break down the internal structure of coral reefs, which is extremely harmful to coral reefs.

Because the chemicals in sunscreen spread to the air and then to the sea, they affect the survival and reproduction of polyps.

All chemical products are extremely harmful to animal life in nature, and sunscreen also blocks ultraviolet rays.

Sunscreen will have some aerosols in it, which will affect the reproduction of polyps, so try to use it sparingly.

Save 1 square meter of coral reef with less sunscreen, sunscreen dissolves in water and can have a great impact on corals.

Anti-cream has chemicals that threaten coral reefs. So we must usually use a little less.

Chemicals in sunscreen, especially aerosols, can disrupt coral reefs' ability to reproduce and eventually lead to their extinction.
