Just reading about correlation between space exploration and bein' a big old vegan. Logistics, shelf-life, weight, safety, stability and efficiency. Closed loop systems etc. Interesting, eh? The future evolution of humanity may require moving away from animal-based diets. Just imagine, in 500 years, children being taught that their ancestors came from a planet they killed through exploitation where they ate the rotting carcasses of other living beings. They'll think we're barbarians. And they won't be wrong.
