How Pollution Creates Dead Zones in the Chesapeake Bay

Miacademy & MiaPrep Learning Channel

This educational video provides a comprehensive look at the Chesapeake Bay watershed, focusing on the ecological and economic impacts of water pollution. Narrated by Caroline, the video explains the function of estuaries as "nurseries of the sea" and details how human activities like deforestation and agriculture lead to nutrient and sediment runoff. It visually demonstrates the process of eutrophication, showing how excess nutrients cause algal blooms that block sunlight, kill aquatic plants, deplete oxygen, and create dead zones.
