If livestock production is replaced precision fermentation, it creates what could be the last major opportunity to prevent Earth systems collapse, namely ecological restoration on a massive scale.
The most interesting developments use no agricultural feedstocks. The microbes they breed feed on hydrogen or methanol – which can be made with renewable electricity – combined with water, carbon dioxide and a very small amount of fertiliser. They produce a flour that contains roughly 60% protein, a much higher concentration than any major crop can achieve -soy beans contain 37%, chick peas, 20%-. When they are bred to produce specific proteins and fats, they can create much better replacements than plant products for meat, fish, milk and eggs. And they have the potential to do two astonishing things. >>>
