Landfill Management and Environmental Impact

The video discusses the journey of garbage from disposal to landfills. It explains how garbage is collected, sorted, and either recycled, composted, or sent to landfills. Landfills are described as structures designed to isolate waste from the environment, but they pose environmental risks by releasing methane and leachate. The video highlights the importance of proper landfill construction and the ongoing challenges they present for future generations.
