There isn't remotely enough grasslands in the US or anywhere else to support populations with natural grazing of livestock.
You're once making faulty assumptions, because you are unable to think in anything other than industrial terms. Human managed, rotated ruminants are therapeutic for the soil, and sequester nitrogen and phosphorus. Which are two of the most industrial industrial ag inputs. Wendell Berry has shown that a family of 12 can self-sustain on 2.5 acres growing their own food, and raising their own meat and growing their food with surplus using practices that actually build up the soil and environment, increase resilience, improve rainfall patterns, and resist disease and pests. This is with no industrial inputs other than some metallurgy that is no longer able to be sourced from traditional methods.
In terms of habitable land, there is approximately 2.8 acres available per person alive today. If you consider this on a an average household size scale, there is more than enough land to go around by a factor of at least 5, maybe as high at 8.
Again, hands will get dirty, there will be some long days of hard work, but there will also be community, with a growing healthy dependence on neighbors. There will be not only enough, but extra for those who struggle, which happens to be the essence of Christianity.
What is incredibly important (and I believe authentic Christian has the best solutions to this) is avoiding what Marx calls, "primitive accumulation", where fewer and fewer people start to amass all the valuable resources. This creates perverse incentives to adopt unsustainable practices, and ultimately inefficiency, ie: 10 cals of petroleum for 1 cal of food. A single human can turn 1 cal of energy into approximately 1.2 cals of food using only regenerative, sustainable techniques. A group of 100 people can achieve 1/1.5 easily using small amounts of animal labor. At this point, diminishing returns start to set in, and as the scale goes up, real problems emerge. Hence the Dunbar number.
Living this way, humans can drastically change the environment for the better. Previously dead, non-arable land can be made habitable on a very short timescale (especially is industrial inputs are used but sparingly). Rainfall patterns can be changed, and biodiversity can be brought to even higher level than the previous "natural" state.
I believe this was Adam's original mandate to "cultivate and keep" the garden of Eden. Man freely decided that forbidden knowledge from evil gods was more appealing, but that doesn't change the original mandate.
If you don't believe me about this, go read some Sepp Holzer, and see what he's done.
