Buy from small local farms.. you know where and WHO your food is coming from. Less footprint on the world, and you support those who work ridiculously hard for their money.
This. Sometimes organic, sometimes not, but I'm fortunate to live in a area where there are many small farmers and a local market that is more functional than touristy. I think there's a big difference in a local farmer who is trying and a mass produced commercial farm far removed from the consumer.
For example, we visit the peach orchard weekly in the summer months and get to talk with the owners. He told me what he sprays, which bugs it is that he has to spray for (and when) and how hard he works to minimize pesticide residue in the fruit.
A close friend is a beekeeper and his bees are the ones who pollinate the orchard. There's a strawberry farm in between, so the honey is peach/strawberry, although I can't taste that in it. Yummy though!
I buy beef that is grass fed, the field is not organic (but not sprayed), and if an animal gets sick and needs them, it gets antibiotics, but they do not have them all the time.
Mennonite farmers use no/minimal chemicals but do not certify their produce/eggs as organic.
The farmer who sells us eggs told me (and I don't know if this is true) that she can't claim her eggs are organic because her chickens are truly free range and she can't certify that the grasshoppers they eat are organic!
When all is said and done, this way of eating is more complicated than just hitting the store for everything. However, it is much cheaper than going to a Whole Foods for everything. Plus--I do feel like our outings are educational and fun--not a vibe I get at the grocery store.
This time of year, there aren't local veggies and I buy both organic and non, depending on price/type. There's a list you can get from Environmental Working Group--
