Mr F. said:
Well, if you read into it, No, it is far from "False". I am going to make this very, very explicit. Most animals reared for food are not reared on pasture land, only eating grass and weeds as part of a cycled agrarian system. Far from it. Those chickens, what are they eating? How about pigs being reared on fishmeal (Which is takin resources from other things). Most animals are reared in a way which is totally unsustainable.
And unethical when you consider the amount of people on earth who are starving. When you consider the fluctuating food prices, Mainly caused by assholes who trade on the futures of staple food crops but partially influened by areas of the world where it is more profitable to produce Soy to export to western markets to feed up cwos and the like than produce rice to export internally to the local population.
I am sorry, but it is hard to argue that the majority of meat on this earth is produced in ways which are far from ethical when you consider the HUMAN cost.
I don't know exactly where you're getting your information from. Chickens and pigs can live, to a significant degree, on refuse - and most everywhere they are raised, they are. That's actually one of the big pros for raising them.
Bovines are, really, mostly raised on free range-lands. The intensive methods used in the US, and to a smaller degree in Europe, are anomalies. I mostly have data on Brazil, so gonna roll with that as an example.
Brazil currently supplies 44.5% of the world's meat export (source in portuguese: http://www.agricultura.gov.br/animal/exportacao) and almost the entirety of Brazil's meat production is, indeed, based on grazing on open fields. Only a tiny, tiny fraction of the meat produced is not free-range, and that is generally for the minuscule "Luxury meat" market.
Brazil is also the third largest producer of soybeans, producing 90.6 million tons of it. The vast majority of the production is for national consumption, with small amounts going towards national livestock feed - animal ration association data indicates 13.3 million tons of soybeans consumed per year. Of that amount, 70% goes towards dairy farms. (source in portuguese: http://www.gazetadopovo.com.br/agronegocio/conteudo.phtml?id=1262122&tit=Industria-de-racao-pisa-no-freio)
Most other non-BRIC third-world countries probably have even less intensive farming, for one simple reason: It is seriously expensive to set up. People just can't afford it.
So, to correct your original statement:
Most animals
in first-world countries are reared in a way which is totally unsustainable.
Even that statement may not be true, as fairly significant chunks of the first world are not into that.
Do agree, though: Non-free-range agriculture is pretty retarded and has to go. Only point of disagreement: Only a tiny fraction of humanity does it, or live off of it, or eat it.
It does, indeed, still harm the rest of humanity to a noticeable degree.
