Check out these picks for organic and natural Halloween goodies from Corey Colwell-Lipson, founder of Green Halloween. “My favorites meet at least one, and ideally all three, of our “3-G” criteria: good for people, good for planet, good for communities. There's also a fourth “G”: good for animals and habitat.” Most often, that translates into products that are organic; contain no GMOs, preservatives, artificial colors/flavors, palm oil, or corn syrup; are fair trade (especially important for chocolate, she says); and are made with whole, real foods.
