Understanding Watersheds: Importance, Pollution, and Local Impacts

This document explores the concept of watersheds, defined as land areas that drain into bodies of water, including lakes, streams, and wetlands. It discusses the components of a watershed, such as people, plants, and animals, and highlights how urban development alters watersheds by increasing surface runoff, decreasing groundwater seepage, and introducing pollution like oil, salt, and sand. The document prompts readers to reflect on their connection to the Chicago River watershed and consider the types of pollution present in their neighborhoods.
