The grasses will breathe, growing, dying back as we eat them, growing again, taking the carbon dioxide out of the atmosphere and storing it in the soil; the grasses will breathe the sunshine into the earth and store it in their roots.

Other top predators have become extinct in many ecosystems due to the density of human activity.
