Animals benefit from a reduction in disease and injury by being less intensively reared. Barn hygiene is improved and thus the likelihood of pathogens is reduced. Yields of eggs or milk are a function of natural feeding practice and are not artificially boosted to unnatural levels using hormones. Birds and animals are treated with respect from birth to death. Manures are not slurried, they are well rotted with vegetable matter to form pathogen free manures which add nitrogen to the soil naturally.
Organic products are more healthful.
Farm workers will no longer suffer from respiratory problems associated with handling farm chemicals. Absence of chemical, hormone and antibiotic residues makes products safer to consume. Absence of synthetic additives in processed foods reduced the likelihood of food intolerance. Organic principles do not permit irradiation. The way that we breed animals for food is a threat to the planet.
