Downed animals are cattle unable to walk because of illness or injury. They are dragged to slaughter using chains and tractors. But you can be sure somebody will be buying them. In fact, let's cut to the chase. How high up you eat on the food chain could affect world hunger.
Hunger is man-made.
We feed almost half the world's grain to livestock, returning only a fraction in meat while millions starve. We're raised on a diet of advertisements promoting beef, ham and poultry as perfect All-American protein. That's a lot of plant-based food that could be eaten by people instead of steers. It is real simple. Eat lower on the food chain, and more people can be fed.
