I guess this idiot thinks that millions of bison were a bad thing environmentally. We'd have never had the soils of the Great Plains without them.

Great point. Millions of bison over tens of thousands of years sure are going to do a great job of fertilizing the soil.

It's not just poop. It's grazing grasses to facilitate forbs with their microbial relationships. Grazing also forces cyclical root die-back which adds organic matter.

Animal disturbance is not only elemental to soil formation, it inhibits successional establishment of perennial cover to retain the region in grasslands. That too builds a deeper soil.

Over 70% of agricultural soils are former grasslands.
