This document discusses entomophagy, or the eating of insects, as a potential food source for the future given the growing global population. It provides a brief history of entomophagy, noting its practice among certain ethnic groups today as well as examples throughout history. The key reasons discussed for considering insects as food are their nutritional benefits, lower economic and environmental costs compared to traditional meat sources, as insects require less water and land. The document concludes that widespread adoption of entomophagy could help address problems of world hunger and global warming, but would require changes in Western attitudes and regulatory approval.
