Eating locally produced food could have some major positive impacts on the environment. By buying locally, you can cut down on the significant greenhouse gas emissions caused by transportation and refrigeration. One study on environmental costs of produce in the UK showed that produce that was transported from outside of the UK used 20x more CO2 than locally grown food. If possible, switching your diet and habits so you can buy locally grown produce can considerably help the environment. There are also economic benefits of locally sourced produce. Farms draw in more taxes than they require in services. It also generates money for your local economy, benefiting your own community rather than giving more money to large retailers. I personally have a small backyard garden with a few lettuce plants, strawberries, lemons, and kiwis and there's a small grocery store near my house that primarily sells locally grown produce. The food is always very high quality and fresh and buying from the market gives money to a local store and the local farms it buys from.
