Ecosystems are regenerated through the agency of plants, capturing energy from the sun and transferring it down into the soil.

Plants are the primary collectors of energy. They are the only way we have of bringing new energy into an ecosystem.

All other organisms simply convert the energy captured from photosynthesis.

Livestock are not the foundational organism to regenerating soil and ecosystems.

Fungi are not the foundational organism to regenerating soil. Neither are bacteria. Or actinomycetes, protozoa, or any other organism. 

These other organisms can be managed to develop an environment where plant energy collection jumps dramatically. Or they can be mismanaged in such a manner that photosynthesis declines in the landscape.

Optimizing sunlight capture increases yields and unavoidably results in regenerating landscapes.

Optimizing soil fertility to increase yields may or may not regenerate agricultural landscapes. With the approach being used in contemporary agriculture, the effect on landscapes has been negative, not positive.

Are you managing for most efficient sunlight capture?

Are you managing to optimize soil function, or sunlight capture?
