An easy way to cut demand and use of AgroChemicals is to support farmers who grow organic foods and grow your own. Even easier, is to grow food that grows like weeds. Amaranth is native to many parts of the world which are now high in mono-cultured production and chemicals are used to kill it off because it persists. Every part of the Amaranth plant is edible and some highly nutritious in raw state. It will even grow in pots in a window sill. Try growing it from seed from a health store. Local seed is the best bet.
