One way to drastically cut down on the shipping and energy used to move fresh fruits and vegetables from one part of the country to another is to reduce demand by growing your own instead. Even if you start small, it can make an impact. If your family eats a lot of something — for example, tomatoes — you can even consider a small container garden for that purpose only.
Either way, a garden can pay off handsomely once you absorb the start-up costs and begin producing your own fresh produce. For tips on gardening on a budget, check out this post on reducing the startup costs of a food garden.
