Organic Farming Is Not Sustainable

Organic Farming Is Not Sustainable

May 16, 2014

"You may have noticed that the organic section of your local supermarket is growing. Advocates tout organic-food production—in everything from milk and coffee to meat and vegetables—as a "sustainable" way to feed the planet's expanding population. The Worldwatch Institute, a Washington, D.C.-based environmental group, goes so far as to say organic farming "has the potential to contribute to sustainable food security by improving nutrition intake and sustaining livelihoods in rural areas, while simultaneously reducing vulnerability to climate change and enhancing biodiversity." The evidence argues otherwise.

A study by the Institute for Water Research at Ben-Gurion University in Israel, published last year in the journal Hydrology and Earth System Sciences, found that "intensive organic agriculture relying on solid organic matter, such as composted manure that is implemented in the soil prior to planting as the sole fertilizer, resulted in significant down-leaching of nitrate" into groundwater. With many of the world's most fertile farming regions in the throes of drought, increased nitrate in groundwater is hardly a hallmark of sustainability.

Moreover, as agricultural scientist Steve Savage has documented on the Sustainablog website, wide-scale composting generates significant amounts of greenhouse gases such as methane and nitrous oxide. Compost may also deposit pathogenic bacteria on or in food crops, which has led to more frequent occurrences of food poisoning in the U.S. and elsewhere."
