Theme: Edible Plants
Item #1: There are over 400,000 known plant species in the world, about 300,000 are edible to humans, but we regularly consume only 200, and 3 crops make up over half of plant calories consumed.
Item #2: Cattails are almost entirely edible, and in fact produce more edible starch per acre than any other green plant.
Item #3: Many species of cacti contain significant stores of water that can be used as an emergency source in the desert.
