  skos:definition "Global environmental systems have been profoundly affected by agriculture throughout the Holocene epoch, but these impacts have been especially pronounced since the Green Revolution began around 1945. The environmental effects of food production include alterations of the Earth's hydrologic cycle, increasing levels of atmospheric greenhouse gases, decreased biodiversity, accelerated rates of soil erosion, and the rapid spread of eutrophication in freshwater and marine ecosystems.
