Earth Day

More than 20% of material sent to the landfill in Chicago by weight is food waste, which decomposes and releases the harmful greenhouse gas methane. Instead, that food waste could benefit the earth by being composted. 

In honor of Earth Day on April 22, learn about the imperiled natural world through Nature, NOVA, and other specials about endangered species, climate change, and alternative energy. Plus, watch a monumental new series on the history of art at your own pace.
