While on Midway, I walked each morning to a beautiful beach I started calling Monk Seal Point. Others say Rusty Bucket because of the military debris scattered along the shore. Plastic Beach might also work..........
This is typical of the beach and pretty much what the north end of the island looks like as you walk along, hoping to see a shell or chunk of coral. Lighters and bottle caps, toys and endless chunks of broken plastic litter this, one of the most remote islands on the planet.
I scooped a teaspoon of sand from this spot. I added a little water. Under a hand lens, I counted more than 150 pieces of plastic. Micro and toxic, these plastics are one with the beach sands and one with the ocean. I'm told that some kinds of plastic absorb PCBs and other poisons that are so common in marine animal bodies. I know that PCBs are incredibly damaging to marine mammals, altering immune systems for example. If anyone knows how they affect fish, do comment.
To help understand and call attention to micro plastics, I've been asking for beach sands from around the world. I will post a note soon about preliminary results. Already, I've seen micro plastic in a sample from the beach near where I live on Marrowstone Island in Washington State. I've also seen micro plastics in beach sands from the outer coast of Washington where visible, larger plastic debris is a major part of the beaches where cars drive out onto the intertidal at Ocean Shores.
SERIOUS SAND is one project of SOAR. It has already been tested with teachers and is a simple, eyeopening way to do some science with kids. Simply visit a beach. Collect sand from areas where the natural and unnatural debris accumulates along the strand line. Add water to a small sample in a glass bowl. View under a hand lens or dissecting scope to check for micro plastics of about 2mm or smaller in size.
You might also find nurdles, the basic ingredient of many plastic products. Apparently, these are transported by ship and often spill into the sea. I'm guessing that far, far, far more plastic enters the sea as waste from our shores. According to the U.S. Fish and Wildlife Service, 10 tons of plastic wash ashore on Midway Atoll each year. Of identifiable plastic, 22% is land based and 18% is fishing industry based. 55% of the land based plastic arriving at Midway is in the form of bottle caps.
Okay. So you found some micro plastic. What can we do? My take on this is to go directly to producers and find ways we can help them reduce or eliminate plastic in their products. One way to do this is to partner businesses with schools. Ask kids to soar into the future with invention contests, encouraging them to create new ways of recycling, designing new products, and imagining some techniques of eliminating existing plastics from the seas.
If you found no micro plastic, this is good. But if you take your students on a walk along a lake shore, riverbank, or ocean beach, chances are good you will be able to do a great job of cleaning up plastic debris. Bring this to a recycling center to learn how much plastic waste accumulates in your community.
As an indoors project, take a look around your classroom or your home. Count the plastic products you use each day. Can you eliminate some for the health of the ocean? Can you imagine a new way of using this same kind of product without plastic involved? If it is a bottle of water, remember how we all used to drink from the faucet? And consider buying a stainless steel, reuseable drinking container. These are starters, but if you are a teacher, think way beyond this. Chances are you have a student in your midst with the best idea possible to help the sands, the sea, and the planet go plastic free.
First thing. You need to get kids excited by doing a little research. Visit sites that explore the ocean plastic issue. View the beauty and the problems at Papahanaumokuakea Marine National Monument. Soar with the Albatrosses to help save their ocean.
Start a new SOAR project and share it with us.
