The United States is positively glowing right now. Too bad it’s glowing with dumps.

As our population grew over the last century, so did our mountains of trash. This map from SaveOnEnergy (pointed out by CityLab) reveals where landfills sprung up in response to that growth. The circles dotting the landscape indicate the size and status of each dump: Closed landfills are indicated with green dots and operating ones with red.

Today, more than 2,000 landfills are operating around the country. Check out SaveOnEnergy’s site for a nifty interactive map that locates landfills near you.
