During World War I and World War II, the United States government asked its citizens to plant gardens in order to support the war effort. Millions of people planted gardens. Emphasis was placed on making gardening a family or community effort - not a drudgery, but a pastime, and a national duty.

Planting a Victory Garden to fight global warming would reduce the amount of pollution your food contibutes to global warming. Instead of traveling many miles from farm to table, your food would travel from your own garden to your table.
