Is Your Sunscreen Killing Our Corals?

YES. Most probably. I have come across this topic many times the past few months and it seems whenever it is brought up, close to no one knows about it and know how harmful most of the sunscreens are to marine life.

As a matter of fact, around 95% of sunscreens in the market are made with chemicals that are directly killing our corals. Is it an important subject to talk about and it is very easy to find an alternative. The active ingredients in a sunscreen lotion are either chemically-based or mineral-based. A crushing majority of them that are available on the market are using oxybenzone, butylparaben, octinoxate or 4MBC in order to block the harmful UV-A and UV-B. Unfortunately, when swimming, these chemicals are dispersed into the sea and attack the corals. They kill the corals’ symbiotic algae that normally provides them with food and grant them those astonishing rainbow bright colours. Without these algae, the corals bleach and lose their protective layer, thus are subject to deadly diseases.

On the contrary, mineral-based sunscreens do not only represent a more responsible choice but also a healthier one. To begin with, compared to chemical-based formulas, they are probably healthier for your skin and body. Until today, the scientific community is still researching on the long-term impact of chemical sunscreen in the human body and they are already known to be inclined to cause irritations. Mineral based formulas use zinc oxide or titanium dioxide to protect your skin. These sunscreens are as efficient but free of harmful chemicals.

Coral reefs cover around 1% of the underwater surface of the globe, but they are home to 25% of all fish species. Scientists consider these colonies of tiny animals as the “Amazon of the seas”; this is why it is so important to preserve them. The only notable drawback of a mineral sunscreen is that they are usually thicker and whiter than chemical sunscreen, so they need a bit more time to be spread throughout your body. It is probably a small price to pay to be sure that you are not harming the ecosystem when enjoying our sea, part of the famous Coral Triangle, the epicentre of biodiversity of corals and fishes on Earth.

Now you know how to choose your next eco-conscious sunscreen!

If you are interested more on the subject, this article was greatly inspired by the video of TED ED on youtube “Which sunscreen should you choose? - Mary Poffenroth”. Their videos are always very informative and easy to watch.

Nakapatay ba an Imo Suncreen sa Ato mga Gasang?

OO. Lagmit gajod. Nakasugat na ako sa ini na hisgotan kapila sa noagi na mga buyan sanan kon istoryahan ini, hapit wayay nahibayo mahitungod nan ini sanan wayay nakahibayo uno ini ka makadaot an sagad sa mga suncreens ngadto sa mga kinabuhi sa dagat.

Gani suod sa 95% sa mga sunscreens sa merkado an hinimo nan mga kemikal na direkta makapatay sa ato mga gasang. Importante ini na istoryahan sanan sajon ra sab ini hanapan nan alternatibo. An aktibo na sagol sa suncreen na lotion mahimo na base sa kemikal o base sa mineral. Arang kahamok sa ila na mapalit sa mga merkado an naggamit nan oxybenzone, butylparaben, octinoxate o 4MBC para matabonan an makadaot na UV-A sanan UV-B. Pero demalas kay kon maglangoy an ini na mga kemikal makanat sa kadagatan sanan moatake sa mga gasang. Mapatay nila an simbiyotiko na lumot sa gasang na sagad naghatag nan pagkaon sanan adton magana na sinaw na kolor na rainbow. Kon waya ini na mga lumot, an gasang moputi sanan mawaya an ija nagprotekta na sapaw, ugsa dali na sila masakit.

Sa pikas bahin, an base sa mineral na mga sunscreen waya lamang nag-representar nan responsable na pagpili kondili mas himsog isab. Para sugdan, kompara sa base sa kemikal na pormula, mas himsog pa ini sila para sa imo panit sanan lawas. Hangtod kuman, an komunidad na siyentipiko naghanap gihapon nan pandugay na epekto sa kemikal na sunscreen sa lawas nan tawo sanan nahibay-an na hinungdan ini sila nan iritasyon. An base sa mineral na pormula naggamit nan zinc oxide o titanium dioxide para protektahan an imo panit. Ini na mga sunscreen haod ka epektibo pero wayay makadaot na kemikal.

An kagasangan nagtabon nan 1% sa ilayom nan kadagatan sa tibuok kalibotan, pero sila huy-anan sa 25% na tanan klase na mga isda. An mga siyentipiko nikonsiderar sa ini na mga kolonya nan gagmay na mananap isip an “Amazon nan kadagatan”; ugsa naman importante na ipreserbar ini sila. An mabantajan na kayaot sa mineral na suncreen kay sagad mas baga sila sanan mas puti kaysa kemikal na sunscreen, ugsa kinahanglan sila nan panahon para ikanat sa tibuok lawas. Gamay ra ini na presyo na bayran para masiguro na waya kita magdaot sa ekosistema samtang naglingaw sa ato mga dagat, na kabahin nan nakilaya na Coral Triangle, an tunga-tunga nan biodiversity nan mga gasang sanan mga isda sa Kalibotan.

Kuman nahibayo na kaw unohon pagpili sa imo sunod na eco-concious na sunscreen!
