paragraph_text: Impacts
  
  Cereal production has a substantial impact on the environment. Tillage can lead to soil erosion and increased runoff. Irrigation consumes large quantities of water; its extraction from lakes, rivers, or aquifers may have multiple environmental effects, such as lowering the water table and cause salination of aquifers. Fertilizer production contributes to global warming, and its use can lead to pollution and eutrophication of waterways. Arable farming uses large amounts of fossil fuel, releasing greenhouse gases which contribute to global warming. Pesticide usage can cause harm to wildlife, such as to bees.
