As someone who was a cheese-aholic for 40 years of vegetarian life I can relate to the start of this newscientist.com/article/mg... article. I have to say that I loved my cheese an awful lot. Now I could not care less about it even if you put some premium quality cheese right under my nose. The article talks of global milk production doubling in the last 50 years, of cheese being a refuge for people who gave up meat (like I did).
Much of the article is about the carbon footprint of cheese, the worst offender being cheddar reaching up to 16kg of CO2. The industry is trying to manufacture the zero-carbon cow, about which I am sure the cow is most pleased!
The article then goes on to the animal rights aspect, talking about repeated forced insemination, since only for the 9 months of pregnancy does a cow produce milk. With that repetition being for all its adult life until it's lactate drops and is deemed unprofitable. Once a cow reaches that point it is killed for burger/sausage meat. I won't go into further details here, but just summarise from a quotation in the article attributed to Marc Bekoff, "dairy farming is hideous."
The article finishes with how dairy farming addresses this. There are two extremes, at one a calf stays with its mother cow and lives a life grass fed. This incredibly inefficient and expensive. The other end is more intensive farming with cows being tethered day and night. This is how cheap cheese gets to the supermarket. It may be inhumane, but it has a lower carbon footprint.
Whichever way it goes dairy is now in the limelight.
