Eco-friendly Protein Sources From Around the World

In certain cultures around the world, creatures like beetles, stink bugs, and grubs are not seen as pests, but as food items.  In places where protein sources are rare, they are a vital part of the diet.  These creatures are quite eco-friendly as food.  They consume relatively little, and do not require grazing land or antibiotics.  Perhaps these crawling, wiggling animals will have a role to play in a greener future.
