People are actually seriously proposing that. Very high in protein, and very efficient at converting feed to protein.
I'm not sure it will catch on fast....
More seriously, we need to be pursuing sustainable agricultural practices. I believe that means treating crop fields as the complex microbiomes that they should be, instead of highly-tilled, species-restricted biomes. Read up on how no-till and low-till farming practices change the soil communities of worms and microbes. It's huge. We need to move away from heavy reliance on pesticide and herbicide for the health of the soil and environment neighboring the fields, not to mention our own.
The thing is, we got to heavy chemical agriculture in part because of a drive to lower fuel consumption by making fewer passes over the field doing mechanical weed disruption. Of course, mechanical weed disruption is the kind of tillage that disrupts the soil biome, so we shouldn't go back, anyway, even if you could magically make diesel fuel cost $0. We need a new way forward to feed a hungry planet in a sustainable fashion.
Pesticide resistant super bugs could probably breed and eat all our crops in no time.
