Humans have destroyed a third of Earth’s farmland in 40 years

In the last 40 years, Earth has lost a third of its farmable land to human-caused erosion and pollution, The Guardian reports. Soil is now blowing or washing away 100 times faster than it can form, and without that soil humans may not be able to feed their growing population, according to an analysis of research published over the past decade. To avert disaster, say researchers, governments need to help farmers adopt sustainable agricultural practices such as rotating land use between crops and livestock.
