2001). Of the 538,000 acres of agricultural land in California urbanized since the Gold Rush, one-sixth has been lost to farming in the few decades since 1990 (Thompson 2009). At present, agricultural land is lost to urbanization at the rate of more than 40,000 acres annually (American Farmland Trust 2007). In less-developed countries, the growth of large-scale export agriculture has an even more ominous effect. Elites in these countries have, for a long time, gained control of land through various and often illegal means to increase production of export crops.
Livestock are also responsible for much of agriculture’s emission of carbon dioxide and nitrous oxide. The nitrous oxide comes from bacterial processing of the nitrogen in livestock manure; the carbon dioxide comes from the rapid decomposition of crop residue in the tilled fields used to produce livestock feed. In addition to producing greenhouse gases, industrial agriculture exacerbates climate change by reducing the ability of the biosphere to hold carbon in a fixed, organic form. At any particular moment, a significant portion of the carbon in circulation—that is, not locked away in geologic structures below the surface—is not in gaseous form in the atmosphere, but present as dissolved CO2 in the oceans and in organic or mineral form in earth’s terrestrial ecosystems.
