The majority of marine debris found around the world is made of plastic and can range from microbeads smaller than a sesame seed up to an 11-ton mass of abandoned fishing nets. Over time these plastics break down into what is called microplastics (smaller than five millimeters in size). There are lots of concerns about the impacts of microplastics such as how do they interact chemically with the marine environment? Are marine species ingesting them? And are chemicals from the plastics moving up the food chain? This is your chance to chat with two NOAA Marine Debris Program scientists on microplastics and what we can, and are, doing to help during the January 12, 2017 Reddit 'Ask Us Anything'.
