So often, the ocean’s problems are invisible, but plastic pollution in the ocean has rocketed up public consciousness in the past few years precisely because it, and the damage it does, is so visible. Once you start looking, it’s everywhere. Over 40% of plastic manufactured every year will only be used once. In Ocean Matters, join oceanographer and physicist Helen Czerski as she explores the impact plastic is having on ocean wildlife, the scale of single-use plastic bottles in London, and an exciting solution found in nature - enzymes that eat plastic.  Want to be a Citizen Scientist?
