I side with Plato, Leonardo da Vinci, Jeremy Bentham, Arthur Schopenhauer, Romain Roland, Pythagoras, Albert Schweitzer, Plutarch and Thomas Edison in believing that the enslavement, exploitation and killing of other species is an immorality and exhaustive regression of cognitive evolution.
The United Nations has been suggestion for years that due to population growth and increasing consumption that we must make a diet change, away from animal products. According to the UN a global shift towards a vegan diet is vital to save the world from hunger, fuel poverty and the worst impacts of climate change.
If society is changed into a vegan lifestil, animals that produce meat, poultry, and fish will be saved. No animal should die for a person's eating pleasure, for it is not only the lives of humans are important. People should be sparing animals' lives instead of only thinking of their own lives.
Even more, they are considered alive. Does that mean that we should avoid eating them too? Saying they, and their sensibilities, are on "another level" or whatever nonsense vegans use to justify their vegetable genocide is stupid.
We need something to eat to stay alive, and historically we were not only scavengers, but hunters also. We are biologically adapted to eat everything we can get. Even meat. How would you justify, if not, that our eyes are in the front of our face (to better estimate the distance to our prey) and not on the sides (which would give us an advantage in spotting predators), then?
Also, the inuits survive with just meat on their diet. Doesn't that mean we are adapted to eat animals? I'm not saying we should avoid eating our beloved greens. Just explaining why eating animals is not wrong. And finally, a lot of other species eat meat too. Why should we allow them to do it if we are not allowed to?
