The One Tomato Project was inspired by the Victory Gardens of World War
II. Victory Gardens

were home-grown vegetable gardens promoted by the
U.S. and Canadian governments during WWII. In 1943, in a radical act of
war support, Eleanor Roosevelt had the front lawn of the White House
ploughed up, and she planed a Victory Garden. This year, First Lady
Michelle Obama has also planted a victory garden at the White House.
During the war, American gardeners grew about forty percent of the
produce eaten in the U.S., all from plots planted in any available
space including front lawns, vacant city lands, parks, and school
yards.
Today, we have enough space to feed everyone, we just have to change
green space to food space.
