Humanity Survives on Eating Grass

Humanity survives on eating grass. We invented technologies to help us extract nutrients from grass. The millstone and the windmill or the roman water wheel were key steps inor development, absolutely. I e, in a oven that we use for baking bread, weare exploiting mechanical power and sroof chemical transformation to release the nutrient in the grass so that we can aally digested. Yes, i love that. And then you go all the way to show, as another example of exactly what we were discussing just now, how we end up, millions of years later, all eating either sereal or toast for breakfast. Ye ye.
