Professor John FitzGerald:

If we consumed no more beef from tomorrow, the emissions would be identical as we would just export more beef. The Senator is right that this would not deal with the matter. I would be very cautious as an older gentleman about going around telling schoolchildren what they should eat. I know somebody went into a primary school preaching vegetarianism, which led to a child taking to vegetarianism but not eating any vegetables. That child ended up in Crumlin hospital.
