From DW Documentary.

Almost 40% of the planet is covered by natural grasslands. In places like the Alps, these landscapes are a "desert" for humans. Why? Because we can’t eat grass, and the steep slopes make plowing for crops impossible. Plowing here wouldn’t just be hard—it would trigger devastating soil erosion. This is where the cow becomes a biological catalyst. They possess a unique superpower: they transform the "useless" cellulose in grass into high-quality protein. But it’s not just about food. As they graze, they stimulate plants to grow deeper roots, turning the soil into a massive carbon sink.
