Understanding Watersheds and Their Impact

Simon Breen, Education Director for the Escondido Creek Conservancy, explains what a watershed is and how human activities like using pesticides, fertilizers, and vehicles impact them. He discusses the consequences of pollution, such as turbidity, algae blooms, and harm to marine life. Breen offers solutions to reduce pollution, including using organic pesticides, managing green waste, and taking public transportation.
