"Striking images show plastic litter in the world’s most remote coral reefs
A survey of 84 coral ecosystems at 25 locations across the Pacific, Atlantic and Indian ocean basins found plastic debris from human activities in almost all of them, both shallow and deep.
The study team, led by marine biologist Hudson Pinheiro at the University of São Paulo, Brazil, set out to survey biodiversity on remote reefs, which the researchers expected to be pristine. But during their sampling, they noticed that “these places are not as pristine as we were thinking”, Pinheiro says. It turned out that 77 of the 84 ecosystems contained macroplastics — plastic items measuring 5 centimetres or more across. The researchers found that this type of plastic waste made up 88% of all human-generated rubbish on the reefs."
