I hear the same arguments all the time. Oh, we evolved because of meat, or, it’s natural to eat meat because life requires life to live. I used the same arguments myself, until one day I started doing the math of all the waste around me and saw how awful mass meat production is. I couldn’t look at my food the same, and slowly eased into a vegan life style starting off part time vegan which was basically all vegan at home, and ate whatever was on the menu when I went out with friends.
Even if we evolved because of a meat diet, it certainly wasn’t in the manner we eat meat today. Today, people probably have meat for every meal of the day. Even a hundred years ago it wasn’t common to eat as much meat as we do today, let alone thousands of years ago when you had to hunt and make the best of what you killed. There was no storage for meat once upon a time ago, and humans didn’t get a kill every day. There was a lot of gathering of other food and eventually growing as well.
As for how natural it is to eat meat, well, there are creatures out there called herbivores and they do just fine, just as there are carnivores as well as omnivores. And yes, it’s impossible to not kill something for food (I’ve heard the argument that we have to kill plants) as everything that fully sustains us includes some type of living organism but we don’t have to do things the way we do today. Plants grow fast, are easily sustainable, and don’t go through the torture animals go through for our luxury of living and eating.
I’ve head the vitamin deficiency argument, too. A quick google search already shows the fault in that argument since meat is not a requirement for B12 and is produced via bacteria. I’d also argue that with the way most of us in North America eat today, that we’re deficient of many nutrients we supposedly need, vegan or not. For those who eat McDonalds 3x (more like 6x) a day because they “don’t have time to cook” I’m sure are getting all the nutrition they need, right? We also have an incredible will to survive, and you can see human survival in places where they don’t have access to all the nice vitamin varieties we’re supposed to have. Might not be ideal, but you can see the extent of how much shit the human body can go through and live without all the fancy stuff we have in the developed world.
Also, wild caught species such as fish are dangerously low year after year as more and more people consume it. Not only do we come close to causing harm to our ecosystem in trying to meet a growing market demand but we continue to expand and expand on these markets. A very important question one needs to ask their self is, since we can barely meet the demand our animal industry and nearly fish species out of existence in the current state of the world, what happens when the rest of the world starts living just like the USA and other developed nations? What then when the rest of humanity demands to eat the same way we do and live luxurious lifestyles? How on earth can we meet that kind of demand? Imagine all the life that would have to die for that.
Check it out. Wild caught fish as an example, can’t meet the demand in the seafood industry. So eventually, they made aquaculture to farm fish. Now, demand for other species is growing, such as lobsters, and they’re developing ways to farm those and other species like tuna (currently not successful, yet…) It should be a wake up call that our current ecosystem can’t sustain our demand for such luxurious things as dead fish and dead animals on our plates. I ask again, what happens when the rest of the world is on par with us? It’s unfathomable.
Something needs to change. If not for ethics and morality, than at the very least, sustainability. We can’t keep going on like this.
