Oceanic plastic pollution comes from a wide variety of sources and it does most harm to wildlife and the economy close to coastlines. Large pieces of plastic can entangle marine animals, while tiny pieces – broken down by the action of water and the sun – cause harm by entering the marine food chain.

Once it has entered the marine environment, wind and global ocean currents can spread plastic particles around the world. As a result, plastics are dispersed across the oceans and can be found in remote locations such as the Arctic, Southern Ocean and deep oceans.

Ocean plastic pollution is an alarming issue due to its persistence, complexity, steady growth and pervasive impacts on ecosystems. Here at the Grantham Institute, we study the sources, impact and solutions to plastic in the ocean, drawing on our world-renowned expertise in engineering, physics and chemistry.
