Sagar Shah gave a number of presentations at JAINA 2017 in New Jersey. Here is one on environmental an ethical issues in modern food production that we recorded . In this talk Sagar presents a compelling comparison of the killing of dairy cows and male calves in meat, milk and cheese, namely that 6 pints of milk = 350 g cheese = 1/4 lb steak (the numbers in the talk below are slightly outdated). A few people commented on how powerful this was, since Jains would never consider eating steak moral. Subsequent to the presentation, he has updated the slides ( 2017.07.03 – Environmental and ethical issues in modern food – how Jainism helps (11 Aug update)) and here are the detailed calculations (Data and methodology – equivalence of beef and dairy in killing cows ) and (Data and calcs on equivalence of eggs and chickens).
