Book excerpt: On a global scale, humans create around 2.6 trillion pounds of waste every year. None of this trash is harmless—landfills and dumps leak toxic chemicals into soil and groundwater, while incinerators release toxic gases and particles into the air. What can we do to keep garbage from swallowing up Earth? Reducing, reusing, recycling, and upcycling are some of the answers. Learn more about the work of the US Environmental Protection Agency, the Ocean Cleanup Array, the zero waste movement, and the many other government, business, research, and youth efforts working to solve our planet's garbage crisis.
