Who knew that there is an industry developing around insects as food? The Gateway Bug presents a fascinating picture of how dedicated individuals are working to save the planet with bugs. For example, crickets provide high-protein nourishment for cattle, reducing the need for the ever-scarcer water needed to grow corn. (There are bug-snacks for humans too, but I choose not to go there.) This is an engrossing, well-conceived documentary that reveals another inconvenient truth. I found it eye opening.
