Thoughts on production of Food

It an undeniable fact that the mass demand for meat and other crops is vast, and with such a bid demand on such a daily basis the way we produce food right now seems like the best way to meet the demand. It all comes down to supply and demand, right? Not quite, at least not in my opinion. It also comes down to the greed of the powerful companies that rule this industry. They look for new and cheaper ways to produce more, in both quantity and mass, of produce. So in the end, it's greed and us that rule the industry.

 Why feed animals grass, when a cheaper food though grains can be fed to it that also fattens it. In a supermarket, don't we look for the beef with the most meat on it? Yes, we do. So in part I understand with the massive amounts of animals and crops that industry produces/slaughters, because if they don't get out that much they will only be angering their costumers. So we have to change our habits, our need for it. I don't mean to say we have to stop all together, but we do have to stop the amount we need and not settle for the cheapest.
 But I do not only have blame in us, but the way in which the slaughter houses kill and raise their animals is truly, in every way, inhumane. I do unferstand that they need a quick way to kill a mass, but their ways aren't effective. Nor do their ways benefit our health, rather, worsen it in some cases. What these big companies must learn to grow, is compassion and care. For the life and the health of the animal, but also of their customers. Don't send our meat you know to be ridden with E.Coli, let the farmer replant his seeds. In the end, it's about feeding us with compassion to those who have to die to give us what we need. It's not about seeing how much money one company can get by misplaying and altering the system, but how sad it that it seems now that that's all that matters in the world to some.
