Sustainable eating doesn’t have to be hard, and it also doesn’t have to be all-or-nothing.

Adopting just a few of the items on this list can make a big impact. For instance, if one person chose to use reusable bags for the rest of their life, beginning at the age of 25, they could save more than 21,000 plastic bags. Point being: You can make a difference.

Go organic

The definition of organic can be a little confusing, but food labels can help. Certified organic foods are grown and processed using farming methods that recycle resources and promote biodiversity and without the use of synthetic pesticides, bioengineered genes, and petroleum- or sewage-sludge-based fertilizers.

Though their benefits to the environment have a long-term payoff, organic foods can be pricier — if you’re on a budget, find out which foods are most worth buying organic, and limit your organic purchases to the ones that make the biggest impact.

Turn waste into a resource. 
If you’ve got the inclination and a little bit of free time, give composting a try and turn food scraps into a resource that keeps on giving.
