So I take it the objective here is to spur a new sector in agriculture?
Are there any other benefits/drawbacks such as potential health or environmental concerns that may occur as a result of such harvesting?
Generally this is vaguely modeled after IRL farm subsides to spur a new sector of agriculture. A health concern would be possibly ingesting some insecticides.
What about potential for destruction of natural plant and bug ecosystems if a particular bug is brought into an area that it doesn't normally exist in, to be raised on a mass scale?
