Get in your greens
Eating lower impact foods generally means eating more vegetables and steering away from a meat-heavy diet. Even if you don't want to go completely vegetarian, consider adding Meatless Monday to your weekly rotation.
Reduce food waste
Be mindful of how much food you actually need when buying and ordering food. In addition, store food wisely to slow down spoilage.
Eat locally
Look at foods grown from local farms through farmers markets to lower the carbon footprint due to transportation.
