It is very easy to start your own garden. If you have room in you yard, which most people do, you can grow vegetables that can feed your family throughout the season. Going your own food can have a huge impact on decreasing your carbon footprint. When you buy fruits and vegetables at the store you may think that since it is a vegetable it hasn't been processed, but the shipping and sorting of the foods take up a tremendous amount of energy. You could now reduce that amount and walk out to you garden and your veggies for dinner! If a garden wouldn't work in your yard, then eat locally. Eating locally can be less expensive and can conserve all of the energy that is used when transporting these goods.
