Grab a pint of local strawberries, blueberries, or raspberries, and you’re doing the planet a favor. Because they perish quickly and have relatively short shelf lives, berries are often shipped from farm to distribution center via air freight, the most fossil-fuel-guzzling form of food shipment, from South America, Mexico, Canada, and even as far off as Poland. You’re also doing domestic growers a favor: According to Food & Water Watch, the United States imports $220 million worth of strawberries, while selling just $1.5 million worth of domestically grown berries.

Oddly enough, buying local onions could help save a farm. A few years ago, the U.S. government loosened trade restrictions with Peru, and the result has been a glut of imported onions that has dropped the price local farmers can get for their crops by half. As a result, domestic onion growers have slowly been cutting back on the number of onions they grow. All of Peru’s onion exports aren’t doing farmers there any good, either. The primary pesticide used on Peru’s onion crops, methamidophos, has been linked to sperm damage in farmers.

Sales of this crop have also benefited from our neighbors to the south. Asparagus imports from Peru have grown steadily over the past decade and now account for 51 percent of the asparagus we consume. The vegetable is now Peru’s largest agricultural export. The USDA requires all shipments of fresh asparagus from Peru to be fumigated with the dangerous pesticide methyl bromide, a neurotoxic chemical suspected of causing cancer. If that’s not bad enough, the chemical shortens asparagus’s shelf life, so it doesn’t even taste good by the time it arrives at the store! The best-tasting stalks are at the farmers’ market, even if the asparagus season is fleeting.

Domestic, imported. Organic, nonorganic. Peaches just don’t taste good any other time of year than in midsummer, the height of their season, because they don’t hold up well during transport. Another benefit to buying local? Pesticides. According to the Environmental Working Group’s Shoppers Guide to Produce, peaches are treated with more pesticides than any other fruit. Buying local means you can grill the farmer to see which chemicals, if any, he or she uses.

Despite the feel-good factor of supporting local farms, where your food is grown accounts for just a fraction of its environmental impact. It’s how your food is grown that matters most. According to a pair of Cornell agricultural researchers, 11 percent of your food’s environmental impact comes from food miles, whereas 83 percent comes from how it was grown, particularly when it’s grown with the greenhouse-gas-intensive fertilizers and pesticides used on chemical farms.

Like organic food, the environmental impact of animal products has more to do with how they were raised than how far they traveled—which is why buying local beef and dairy is important. Animals raised entirely on grass produce 8 percent fewer greenhouse gas emissions and 30 percent lower ammonia levels than corn-fed animals raised in confinement. Since the term grass-fed isn’t always reliable (it’s not well regulated), local venues allow you to ask farmers direct questions about how their animals were raised.
