What are the major environmental issues today associated with agriculture? - Tony Grayson, Newark, NJ Westport, CT - infoZine - E/The Environmental Magazine - What amazes many environmental advocates to this day is how the widespread adoption of synthetic chemical pesticides, herbicides and fertilizers for use in agriculture was dubbed the “Green Revolution," when in fact this post-World War II paradigm shift in the way we produce food has wreaked untold havoc on the environment, food quality and human health.
Agricultural output has certainly increased as a result of these changes, but with the vast majority of the world's farms now relying on petroleum-derived synthetic chemicals to grow crops and petroleum-derived fuels to drive the engines of production—modern agriculture has become overwhelmingly toxic to the atmosphere and is hastening global warming. The Intergovernmental Panel on Climate Change (IPCC) reports that agricultural land use contributes 12 percent of global greenhouse gas emissions; here in the U.S. almost 20 percent of our carbon dioxide emissions come from agricultural sources.
Intensive use of chemicals isn't good for our nutrition intake, either. Overworked, depleted agricultural soils generate fruits and vegetables with fewer nutrients and minerals than those produced by farmers decades ago. And much of the food we eat is laced with chemicals that end up in our bloodstreams.
Beyond its effect on the food we put in our bodies, modern agriculture generates large amounts of nitrogen, phosphorous and other fertilizers running off into our streams, rivers and oceans, compromising not only the quality of our drinking water and the health of riparian ecosystems, but also causing those huge oxygen-depleted ocean dead zones we hear about in coastal areas such as the Gulf of Mexico.
