Ok but remember that that's by-weight. Energy drops by a factor of 10 for each trophic level. One pound of meat requires 2.5-3 pounds of grain and 1847 gallons

Ok but remember that that's by-weight. Energy drops by a factor of 10 for each trophic level. One pound of meat requires 2.5-3 pounds of grain and 1847 gallons of fresh water.
It also requires 3 pounds of grain and 4.5 gallons of water per gallon of milk and dairy is almost 20% of the waste.
The scale of this waste is mind-boggling.
- pfdietz 4y agoYes, meat is at the top of a trophic pyramid, so it reflects much more production of plants (to feed the animals). If meat is used more efficiently, then that means there's much less "waste" going on there (except the inherent inefficiency of making meat from plants, but that's not what we're talking about with that 50% figure.)
