Here are some straightforward ways to make your carbon footprint lighter just by altering your food choices.  The best part:  these solutions aren't expensive, time intensive or difficult.  Following them could also improve  your overall health! 

Eat less beef, pork, and lamb.  Producing 1 pound of beef uses up to 29 times more water than 1 pound of chicken and 50 times more water than 1 pound of soybeans.  3 liters of oil are required to produce 1 pound of beef.

Eat out at restaurants less often.  On average 11-13% of food served in a restaurant goes to waste.  The lighting, cooling, operation of the restaurant, and energy used to drive there is much more taxing on the environment than if you were to cook the same meal at home.

Eat fewer dairy products.  Together with meat, dairy products are responsible for emissions such as CO2, nitrous oxides and methane...all big contributors to global warming.

Drink fewer soft drinks.  200 billion beverage containers were sold last year, and over 130 billion of those ended up in landfills or incinerators.  If all the beverage containers discarded last year had been recycled, 15.6 million metric tons of greenhouse gasses would have been avoided.

Eat seasonal and local fruits and vegetables.  Importing food by air has a carbon footprint 6 times larger than by ground.  Fresh fruits sold in the winter are often imported or grown in greenhouses, both of which require significant energy use.

Eat fewer packaged snacks and junk food.  More than half of all plastic packaging is used to package food.  One third of the energy used to produce food goes to snacks, candy and soft drinks.

Upgrade to an energy efficient refrigerator.  Your fridge is likely to be the biggest energy sucker in your house, using up to 5 times as much electricity as your television.
