He is a vigorous critic of factory farming, noting that "much of the current treatment of animals in the livestock trade makes the consumption of meat produced through such cruel conditions halachically unacceptable as the product of illegitimate means." In addition, he has argued that the waste of natural resources and the damage done to the environment by "meat production" make a compelling Jewish moral argument for adopting a vegetarian diet. He has written extensively on a wide variety of interfaith issues.
