Americans throw away about 10% of the food they buy at the supermarket.

bags full of food into landfills every year. (21)

One pound of red worms can consume half a pound of food waste every
day. (26)

Recycling an average-size family's yard waste can make about 300-400
pounds of finished compost, or humus, a year. (21)

Thirty-five million tons of yard trimmings (including grass, leaves,
and tree and brush trimmings) are generated in the U.S. annually. Each
year, 12% of the yard trimmings produced are composted. (62)

Fallen leaves contain 50-80% of the nutrients that a tree extracts from
the Earth. By composting them, we're helping the earth replenish
itself. (21)

Grass makes up 70% of all yard waste. If grass clippings are short
enough, they quickly decompose and supply the soil with nitrogen and
carbon. (21)

When yard waste is buried in landfills, where there is not much oxygen,
it releases methane gas, a powerful greenhouse gas that contributes to
air pollution and global warming. Methane and other toxins can also
condense into liquid and leach into groundwater. (21)
