By 2030, Coca-Cola products will account for an estimated 602m kilograms of plastic waste entering the world’s oceans and waterways each year, according to a stark new analysis published Wednesday by the non-profit Oceana.

That is enough plastic to fill the stomachs of 18m whales.

The report arrives amid mounting concerns over the human health risks posed by the spread of microplastics, which scientists increasingly link to cancer, infertility and heart disease.
