Biologists in Rio de Janeiro studying the presence of microplastics in marine life off the coast of Brazil's postcard city have found that the impact of plastic pollution is far worse than they had feared.
The team of biologists don wetsuits and oxygen canisters to dive into the tropical waters around Rio and sample marine life from the ocean. They then measure the quantity of microplastics found inside the organisms in a laboratory.
Even sea urchins extracted from what was thought to be a clean area surrounding the Cagarras islands - designated a natural monument since 2010 - show traces of plastic on the inside, the researchers said.
