Coral reefs are among the most biologically productive and diverse of ecosystems, and directly sustain half a billion people. But some 60 percent of these reef systems are threatened by a deadly combination of climate change, industrial pollution and excess UV radiation.
...Chemical compounds in sunscreen and other personal skin care products have been detected near both sea and freshwater tourist areas. Previous research has shown that these chemicals can accumulate in aquatic animals, and biodegrade into toxic by-products.
Researchers led by Roberto Danovaro at the University of Pisa in Italy added controlled amounts of three brands of sunscreen to seawater surrounding coral reefs in Mexico, Indonesia, Thailand and Egypt.
Even small doses provoked large discharges of coral mucous -- a clear sign of environmental stress -- within 18 to 48 hours. Within 96 hours complete bleaching of corals had occurred.
So, basically, pollution makes us more and more susceptible to cancer-causing UV rays, which makes it more and more necessary to wear sunscreen, especially at the beach of course...which, along with the pollution, fucks up the coral reefs.
I'll just never go outside again, okay?
