Earth Is Rapidly Losing Its Farmable Land

In 2015, intensive farming is rapidly becoming unsustainable. Nearly 33% of the world's arable land has disappeared in the last four decades due to pollution and erosion, the latter of which often results from deep ploughing. Scientists from the University of Sheffield's Grantham Centre for Sustainable Futures warn that our available soil can't support our rate of population growth. They recommend a multipronged approach to a more sustainable farming model, one that includes "no-till" agriculture, maintaining symbiosis between crops and soil microbes, and even making fertilizer out of human sewage.
