- As long as I don't touch them it cant hurt them, right?
- We are about to go scuba diving. Don't put on sun screen .
- James Cook University at ARC Centre of Excellence for Coral Reef Studies, Director of the Professor Terry Hughes "We surveyed 1,036 reefs from the air during the last two weeks in March, to measure the extent and severity of coral bleaching throughout the Barrier Reef region,” said Bleaching occurs when coral experience periods of unusually high sea temperatures. He later said that "severe bleaching has struck all three regions". In the past El Nino conditions to have bleaching happen. But as summers get hotter and hoter this is not longer needed. The Australian Bureau of Metrology shows the temperature anomaly's are warmer then ever, siting a 1.25 degree Celsius anomaly in 2020 on average .
- Algae near the creatures can soak up the toxin and blunt its damage. That also means that bleached coral, heat-stressed corals, which turns reefs white, reefs lacking algae may be more vulnerable to death. . The conversion of oxybenzone to phototoxic glucoside may prove just as harmful to reefs as climate change in the near future.
- Wrong. Sea anemones can turn common chemicals in sunscreen, oxybenzone, into a toxin.
- So the chemicals in the sun screen can releases a toxin that can harm already bleached coral and that mixed with the increasing sea temperatures can lead to more bleaching of coral reefs?
- Yes, so when you go to the beach you should try to use non-oxybenzone sunscreen.
- The findings hint that sunscreen pollution and climate change combined could be a greater threat to coral reefs and other marine habitats than either would be separately, says Craig Downs, a forensic ecotoxicologist with the nonprofit Haereticus Environmental Laboratory in Amherst, VA.
