More than half of all the Thanksgiving food waste comes from two staples: turkeys and milk. The U.S. Department of Agriculture reports farms breed around 200 million turkeys each year; 46 million of those are slaughtered for Thanksgiving. The entirety of discarded Thanksgiving food drains more than 100 billion gallons of water, enough for 18 showers per person in the U.S. Food waste climbs across the entire holiday season, but Thanksgiving leads the way. In terms of methane emissions released into the atmosphere, more than half can be attributed to the landfilled food waste.
