A great many materials can impact the environment in a negative way-and while the by-products of manufacturing are a significant factor, pollution can also consist of discarded and post-consumer items. This program explores how pollution can affect the air, water, and land in the form of gases, liquids, and solids. Viewers learn about substances that constitute pollution, such as petroleum products, greenhouse gases, blue-green algae, plastic, street litter, pet waste, and fertilizer, to name a few. The film also explores how a sustainable future depends upon the willingness of individuals to make informed and responsible decisions when purchasing, using, and disposing of goods.
