> Many places outside of the US do indeed grass/free graze feed. There is absolutely no environmental cost here. In Brazil huge tracts of the Amazon are converted into grassland every year for cattle grazing. This is not environmentally free. This has turned the Amazon from a carbon sink to a carbon source. And the density of ruminants on grasslands is vastly different if those ruminants are raised for meat instead of fending for themselves. And, of course, ruminants emit methane. Just burning the grass every year would be better for the environment than feeding it to cattle.
