Foods With the Worst Environmental Impact (24/7 Wall Street)

"When it comes to the impact certain foods have on the environment, it's not surprising that meat and dairy products top the list. But you might be surprised that foods we've been told are good for us may not necessarily be good for the environment. To find the foods with the worst environmental impact, 24/7 Wall St. reviewed data from the research article, "Reducing food's environmental impacts through producers and consumers," published in Science magazine. Foods are ranked by greenhouse gas emissions in kilograms of carbon dioxide equivalents per kilogram of food product. Impacts from food production include water use and water pollution, depletion of natural resources, greenhouse gas emissions, and environmental pollutants. We also added from the research GHG emissions per nutritional unit as noted (100 g protein, 1000 kcal, etc.). Land use is the area occupied to produce 1 kg of product, in meter squared a year. Freshwater withdrawals include several sources." - 247wallst.com
