An estimated 4.8 to 12.7 million metric tons of plastic enter the ocean each year — but this is not nearly the extent of ocean pollution. Oil spills, ocean mining, agricultural runoff, toxic chemicals, maritime transportation, sewage, and leaking unexploded munitions all have both direct and indirect detrimental health impacts to ecosystems across the globe and the species that rely on them. ePollution is working to capture broad trends on a global scale to better understand how pollution is impacting our ocean and to stimulate new research questions.
