The problem of plastics in the ocean has been receiving a lot of attention recently. You might even say it’s “trending.” As it should be. Ideas about how to clean up the mess are circulating around the internet, including input from professional ocean scientists on how likely these ideas are to really be effective. But the cutting edge of scientific inquiry is assessing the extent to which plastics in the ocean – especially tiny fragments called microplastics – are impacting marine life. A recent study suggests it’s not just fish that might be eating plastic.

As the Director of Ocean Conservancy’s Trash Free Seas Program, I’ve had the opportunity to meet people who care about the ocean and are making a difference for the communities that depend on it. However, I’m always surprised by the number of misconceptions about ocean plastics.
With many people visiting the beach this summer, not to mention all the coverage that ocean plastics has received recently, it’s a great opportunity to clear up some of these myths:

Plastic in our ocean — I think we can all agree this isn’t a good combination. The question is what do we do about it? This year, Ocean Conservancy and our partners collected the largest amount of trash in the 28-year history of our International Coastal Cleanup. In that time, volunteers have removed more than 175 million pounds of trash, much of it plastic, from beaches and waterways around the world. From this first-hand experience, we know the problem is getting worse, and it goes deeper than you might think. The good news is this is a problem we can fix. It will require a new approach to how we deal with plastic pollution, but it is a global issue we can and must solve. Let’s consider the facts. In the next 25 years, ocean plastics could grow to 300-500 million tons, or about one pound of plastics for every two pounds of fish in the sea. So where does it all go? We can’t yet say for sure, but when plastic fragments into smaller, bite-sized pieces, we do know that it is being ingested by fish, sea turtles, marine mammals, and a host of other ocean creatures. Because plastic particles adsorb pollutants in concentrations that can be 100,000 to 1 million times greater than that found in surrounding seawater, the implications to the health of marine life are profound and deeply troubling.
