Transporting food from where it is made to where it is eaten emits greenhouse gases from transportation vehicles. The distance the food travels has been increasing over the last fifty years and now travels about 1,300 miles, according to the National Sustainable Agriculture Information Service. Chris Weber of Carnegie Mellon University, lead author of a recent study on “food miles,” claims that “83% of food’s greenhouse gas emissions come from the growing and harvesting of food.” Another way that the production of food affects the environment is that due to fossil fuel combustion and the use of industrially produced fertilizers are and increasing cause of the loss of biodiversity and ecosystem dysfunction. The total amount of reactive nitrogen in any environment has doubled globally since the pre-industrial era. “Agriculture contributes 50-80% of the total nitrogen load transported into freshwater ecosystems and ultimately coastal waters and seas.” Habitats in the North Sea and Baltic Sea are being considered to be in a bad
