NASHVILLE, Tenn. (AP) — The Tennessee Advisory Commission on Intergovernmental Relations voted Wednesday to begin a comprehensive study of litter pollution in the state.

The Tennessee Wildlife Federation, which advocated for the study, said in a news release that $15 million in taxpayer money is spent to clean up litter each year. In spite of that effort, the Tennessee River contains more microplastics per gallon than any other studied river in the world, according to the group.
