Recently, I've been thinking about how wrong eating meat really is. Not just for the animals either.
If you believe in science, which I hope you all do, then you know about how our emissions are effecting the climate of this planet. Livestock produces 18% of our CO2 emissions, 37% of our methane production and 65% of our nitrous oxide emissions. In addition to this, it produces 64% of our ammonia which contributes to acid rain. We have artificially increased the number of animals that would normally exist in those environments, and it is causing damage.
Meat, when compared to other sources of protein, are just not good for us, especially considering how much we consume. Although there are ways to have a healthy nutrient rich diet that includes meat, there is no reason to do so as you will lack nothing if you supplement meat for alternatives.
Lastly, the animals. The animals we eat live just to die, and not only that they are tortured from the day they are born till they are killed. Any reasonable person knows, even if they believe killing an animal to not be wrong, that this kind of torture is evil.
So what are we left with? What are the pros? It's bad for the environment, it's bad for us, and it's bad for the animals. Why do we eat meat? Because we like it. When we were hunter gatherers it made sense to eat meat, in a sense the animal was gathering for you. But these days we have more than we ever need in terms of variety in order to live healthier, longer lives devoid of meat. If you will not change, at the very least you must admit the selfishness of meat. Something we have no need of, yet sacrifice so much for. Our drug of choice on mass.
PS. One caveat: hunting mitigates most of these issues. With no industry there is no torture and no increased emissions. The meat is leaner, so although it may not be healthy, it's healthier, and the lack of readily available meat regulates it's intake.
PPS. I'm not a vegan, just someone slowly weaning off this addiction.
