Many people want to help protect our oceans—but what about our lakes, streams, ponds, and rivers? Despite making up less than half a percent of the world’s total water supply, freshwater is the lifeblood of human civilizations and critical aquatic ecosystems. Fortunately for us, there is a diverse array of biota working hard to keep these vital waters clean and healthy. In this short film by Freshwaters Illustrated, dive into a busy tropical stream ecosystem and learn how shrimp, crabs, and other invertebrates are creating a nutrient-rich environment for wildlife to flourish and humans to enjoy.
