If farmers markets are inaccessible or not affordable, another great thing you can do for sustainability is to focus on eating what’s in season, either locally, regionally, or nationally, focusing on products produced in the United States.
Did you know that by 2020, the USDA predicts that 75% of our fruit and 50% of our veggies will be imported? This could be devastating for US farmers, especially small diverse producers. This could also be devastating for the environment, and lead to unethically produced food if that food is sourced from countries with weak or low environmental and labor standards.
The Seasonal Food Guide is a great resource that provides you with the information you need to eat seasonally, based on your location.
