I think it's more because the medium used to grow the cells has to be so heavily processed it results in more waste. A chicken will grow in a dirty yard with enough water and corn meal while scratching for bugs and worms. A cell culture requires a nutrient bath that is completely sterile. So instead of just feeding the corn to the chickens you are processing a ton of corn to produce glucose and such... I think eventually they will create bio reactors that can process corn like a chicken can, but it will essentially just be a chicken without a brain. Meat is honestly disgusting when you think too much about it.
