Why bother buying locally? You can buy all kinds of food from everywhere in this age, so what's the benefit? While big industry food production may seem like a good idea at first glance, there's more benefit to keeping it local.
Unlike large scale food, which tends to just do what's best for the crops rather than the consumer, local producers use things that they'd eat themselves, and will probably tell you what fertilizers and pesticides they may have used.
When you buy from companies, that's right where your money goes back to. The company.
When you buy locally, the money gets funneled back into the community, to the farmers and to the people the farmers buy their supplies from in the community.
In the end, these are reasons to keep your food purchases local. While the large scale food industry does have its benefits, I believe the stated reasons prove that local food is the better choice.
