Here’s a blog post containing a thought experiment about the ethics of vegetarianism that I found quite interesting. It was also written by a watcher of my blog; this blog is small enough that I do at least glance at each person who watches me. You are all important to me. I’d recommend reading the link but here’s a really condensed version of what it says.
If you were on one of two train tracks and were told continuing on your current would result in you hitting and killing a pig but you could change tracks to one where you would hit and kill a bean plant, most people would rather hit the plant. That’s an ethical decision where most people value animals more than plants. This is analogous to the situation in a shopping centre where you have the option of either buying ham or beans yet in that situation people do not go for the beans as often. This means at some point there is an inconsistency in the ethics of those people that would eat meat rather than plants but still avoid killing an animal when food is removed from the equation.
The other link I’ll share is a more practical one. Clean drinking water is a fairly rare commodity, particularly in Africa. A vegetarian diet can be produced with less water than a meat-based diet. This means become vegetarian (or at least reducing the amount of meat eaten) would have benefits with regard to water availability. This article shares that some water scientists are suggesting that mankind will be forced to follow a primarily vegetarian diet by 2050 in order for there to be sufficient water for everyone.
