8. Waste less.
The USDA estimates that Americans throw away up to 40 percent of the food they buy. To cut down on your waste, try to purchase only what you need, cook only what you’ll eat, and freeze or otherwise preserve as much as possible.
Get in the habit of composting food scraps, too. If your local waste management service offers curbside composting, use it. Otherwise, set up a simple home-composting system and turn those food scraps into potting soil.
You can also reduce the amount of food packaging you toss. Buy minimally packaged foods, forgo single-use items, and store bulk items in reusable bags or sealed jars.
