There is no 'they'. Beef production will not decrease for a long time. Or rather it will in years like 2025 (USA) when regional weather is adverse. There is no 'they' forcing consumption of insect protein either. However I expect more to be used for chicken and fish feed. Describing that in positive marketing terms is somebody else's problem. Insects produce protein with remarkably low greenhouse gas footprints, and the good species are much more omnivorous than we are. If a fella raised chickens outdoors, it would be a great challenge to prevent them from eating insects. That may be a marketing 'hook'.
