Your first point is very valid, as anyone who has ever lived near a confined feeding operations can tell you which way the wind is blowing by the eye watering stench. During my first master’s degree I worked with a large agribusiness group to use drones with airborne lidar to measure from the air the depth of fecal material in open feedlot pits. We would fly over and take millions of data points then come back a few weeks later and fly the same plot the difference in elevation was the depth of manure. we then calculated how many METRIC TONS of manure would need to be backhoed out and how many dozens of 18 wheel trucks. The depth of manue was measure in feet it compacts to a solid mass in the sun and heat only heavy equipment can excavate it. all that biowaste has to go somewhere usually sanitary landfill as it is not in the right conditions for digestion via fermentator.
No freaking way. Not for food reasons, but for control reasons. Get people eating this stuff, start reducing cattle because of global warming, then when lab meat is fully implemented, shut off the spigot.
