Unfortunately - and this is the problem - it is incredibly inefficient to raise animals properly. Almost any ‘humane’ animal products that you can think of have very harmful practices embedded in them.
Firstly - the animals having the best possible life right to the moment of death would still allow things like lamb. Surely giving a baby the best possible life before killing it young is still barbaric?
Secondly - secondary animal products would still require harmful practices. For a dairy cow to produce milk she has to be pregnant / have a baby. Some farms produce ‘humane’ dairy which involves allowing the mother and calf to live together, but then it also requires them to sell the male calves to be killed for veal because… what else would a male calf be for?
And finally, onto the point of inefficiency. Do you have any idea how many chickens are killed every single day to supply our food system? You probably do, but you may be unaware of what that means - the Earth does not have enough land possible to raise these chickens, it is physically impossible and that is just one farm animal.
So the future of a humane world for animals either involves quality synthetic meat, or everybody is suddenly happy to go vegan, or more likely; everybody remains carnivorous and we continue to torture animals.
I wasn’t familiar with that. When I wanted to see if I could buy ethical cheese I found one farm which reared calves with mothers, and read that although everything else they do seemed to be ethical, they did sell their male calves to be used for veal. That may have been incorrect and if it was, I was unaware.
The cheese was also extremely expensive too, like 10x the price of normal cheese.
