A small group of kayakers paddle out into the waters of North America’s largest river on a cloudy Saturday morning. One of them sets a small plastic bottle adrift on the choppy surface. With a mysterious antenna protruding from the bottle’s side, the current carries the miniature vessel away to a fate unknown. It’s a high-tech twist on the classic message in a bottle. Except this message can shed valuable information on how plastic pollution affects our waterways.
The Missouri Department of Conservation (MDC) St. Louis Region Stream Teams are helping in a big way with a unique initiative to bring greater awareness of the impact plastic trash has on our watersheds, and ultimately, our oceans.
A cooperative of mayors along the Mississippi River called the Mississippi River Cities and Towns Initiative (MRCTI) has partnered with the United Nations Environment Program, National Geographic Society, and the University of Georgia to fight plastic pollution along the Mississippi. The resulting program, called the Mississippi River Plastic Pollution Initiative (MRPPI), is launching a pilot with three cities along the upper, middle, and lower Mississippi. St. Louis represents the middle area, with St. Paul, Minn., representing the upper portion, and Baton Rouge, La., stands in for the lower Mississippi. This pilot program is set to expand to the entire Mississippi watershed in 2022.
Data collection is the first phase of the initiative to find out how much trash, and what kinds, are making it into the Mississippi–along with how exactly it travels through our waterways.
