Beyond our overconsumption problem, landfills themselves are toxic. They’re responsible for 16 percent of methane emissions in the US, and methane is 30 percent more powerful than average greenhouse gases like CO2. Because landfills aren’t aerated for proper decomposition of organic material, the organic matter is stuck in limbo, releasing methane into the atmosphere. Furthermore, toxins from cleaners, batteries, small electronics, and other items that shouldn’t be landfilled leach into the soil and can run off into the ocean and groundwater when it rains.
