Styrofoam is a brand name for a type of expanded polystyrene foam, commonly used for insulation and packaging. It is lightweight, durable, and resistant to moisture, making it ideal for protecting fragile items during shipping. Styrofoam is also used in disposable food containers, cups, and plates due to its insulating properties. Despite its usefulness, Styrofoam is not biodegradable and can contribute to environmental pollution. When discarded, it can break into small pieces that are difficult to clean up and can harm wildlife. Many communities are working to reduce Styrofoam use and promote more sustainable alternatives.
