This document discusses improving the efficiency of food production by comparing free-range and factory farming methods. Free-range farming has advantages like less stress and disease in animals, better tasting meat, lower costs, and higher productivity. However, it also has disadvantages like being more labor-intensive, expensive to feed animals, and animals are more susceptible to climate. Factory farming has less disadvantages but is also less humane.
