Sunscreen- Not Climate Change- Killing Reefs

42-34720580

The equivalent of one drop of the active ingredient in sunscreen into 3 1/2 Olympic swimming pools of water is enough to kill corals. Scientists discovered that it is this, not “ocean acidification” or warming allegedly caused by CO2 that is damaging the world’s coral reefs.

From WUWT:

Oops! It may not be ‘ocean acidification’ killing coral after all – common chemical found in sunscreen is poisonous to coral reefs

From the AMERICAN FRIENDS OF TEL AVIV UNIVERSITY and the “settled science” department:

Sunscreen is proven toxic to coral reefs
Tel Aviv University researchers discover chemical found in most sunscreen lotions poses an existential threat to young corals

 

The daily use of sunscreen bearing an SPF of 15 or higher is widely acknowledged as essential to skin cancer prevention, not to mention skin damage associated with aging. Though this sunscreen may be very good for us, it may be very bad for the environment, a new Tel Aviv University study finds.

New research published inArchives of Environmental Contamination and Toxicologyfinds that a common chemical in sunscreen lotions and other cosmetic products poses an existential threat — even in miniscule concentrations — to the planet’s corals and coral reefs. “The chemical, oxybenzone (benzophenone-3), is found in more than 3,500 sunscreen products worldwide. It pollutes coral reefs via swimmers who wear sunscreen or wastewater discharges from municipal sewage outfalls and coastal septic systems,” said Dr. Omri Bronstein of TAU’s Department of Zoology, one of the principal researchers.

The study was conducted by a team of marine scientists from TAU, including Prof. Yossi Loya, also of the Department of Zoology, the Haereticus Environmental Laboratory in Virginia, the National Aquarium (US), the US. National Oceanic & Atmospheric Administration, Ben Gurion University of the Negev, and other labs in the US.
