When plastic pollution breaks down into smaller pieces, it becomes microplastic. Microplastics are less than 5 millimeters long. For a visual representation, think of a sesame seed. Now imagine trillions of sesame-seed sized plastics floating in the ocean every day, with more continually added from various sources. Microplastics are all around us, and yet many people don't know what they are — or how prevalent they are. That's why raising awareness and educating others about the threats of microlastics is so vital. #4ocean #plasticpollution #microplastic
