I love how everyone talks about becoming vegetarian when you (have to) eat less meat or even very little. Most people about 50 years ago only had money to have meat like once per week, there were times people were just mostly living of fruits and vegetables, this didn't mean they were vegetarian, just meant they couldn't afford a lot of meat.
That's where we need to head towards anyway, let's ignore the whole water thing for now, what's much worse is the fact that the diseases animals have, are getting worse and worse, the way we produce meat is just absolutely horrible for our health, we need to stop putting so much crap in them, we need to stop trying to make them grow faster then nature allows, we need to stop putting them in small holes and just allow them to live like they should, have some freedom, have proper food etc.
Yes this will raise the prices of meat big time, yes it will be the end of McDonalds, KFC, BK etc etc and most people will only eat meat once or twice per week, but hey, it will be safe, will be much healthier, taste better and will force us to eat healthier other foods.
