Study: People are altering decomposition rates in waterways

A new study co-authored by RBC Associate Director Krista Capps and Affiliate J.P. Schmidt gathered data from 550 rivers across 40 countries and found that human intervention increases the rate of decomposition of plant matter, depriving freshwater life of food at a faster rate than usual, as well as potentially exacerbating climate change.
