This is a cycle that only works when there is a healthy cycle. This is only the case in the rarest of cases... Most of the time, soy and other cheap, fast-growing grains like wheat are grown and fed to the animals. Especially in winter. Most cows have never seen fresh pasture grass or touched grass with their hooves. You see that in picture books...or on very few farms.
Most of the time, the land is flooded with animal excrement. This leads to: nutrient surplus and soil damage, groundwater pollution, eutrophication of water bodies, plant damage, etc. And not only that, but also all the antibiotics and hormones that end up in the water and so in our bodies... We really need to wake up and take a look at reality...! 

 Sure, sure but more are turning away from that. As am I. I also think that anything that comes from monoculture is bad, and that is only a recent human "invention." it will pass in time. 

But, more to the point of this conversation, locally grown meat is better for everyone and everything than having everyone on the planet stay eating vegan all at once. We don't have enough arable land for that to do it in a sustainable manner, and to do it sustainably, animals must be integrated into those systems, so... I still see no reason to not eat meat.
