I am reading a book, Soil Science Simplified, and it describes massive losses to our soil from crop tillage and ploughing that is required to grow crops at scale. We are rapidly depleting our top soil and without top soil humans and animals and insects will experience massive famines and die offs. Cattle and other animals can be raised on perennial pasture that actually builds the soil rather than depleting it. Eating their meat is much healthier for the soil than growing vegetables and then tilling the soil. Am I right?
