Also, agricultural chemical overflow gets into the water supply and contaminates our rivers, lakes, and even our drinking water. The EPA has found 98 different pesticides in the groundwater of 40 states, contaminating the drinking water of over 100 million people. Organic methods preserve biologic diversity and help safeguard the world's future food supply. Chemical farming methods usually rely on a single variety of a crop, planted on a huge amount of acreage. A single pesticide-resistant strain of a plant virus can literally wipe out an entire crop.
Organic methods rely on diverse varieties, and are therefore less risky.
Also, most organic farms are small family farms. Buying organic preserves a rural way of life, and the families that make up that way of life. Purchasing organic products now ensures more organic choices, at more reasonable prices, in the future. Ten years ago, the prices on organic produce were much higher than today. As the organic movement grew, prices came down and will go down even further.
