What would happen if you took 20,000 human animals and divide them into two equal groups. Make them all, say, 10 years old and equally divided between the sexes. So...you have 2 groups of 10,000 humans each (who are all 10 years old). Now...for the next 50 years one group can only eat plant based foods and the other group can only eat animal based foods. The only other stricture or condition is that no fire/heat can be used on the food. In other words, no cooking or any other application of heat to the food is allowed.
What would the groups look like (in terms of health, survival rate, etc) in 50 years? The survivors from each group would be 60 years old.
As a variant, do the same thought experiment except this time allow cooking. Actually you can find folks who have done at least the plant based food side of it...for example....Donald Watson founded the Vegan society in 1944 and died in 2005. That means he apparently lived at least 61 years on only a plant based diet. I don't know of any members of a group that only lived on an animal based diet...there might be...I just don't know about them.
It isn't difficult to see that healthy survival (e.g., Donald Watson) is easily possible on a purely plant based diet...but healthy survival for 61 years on an purely animal based diet is rather unlikely.
|I can't vouch for accuracy here, but it is interesting.|
So...next time someone trots out the notion that humans are "carnivores" you might suggest the thought experiment (the one without the cooking) and see if that doesn't throw a little kink in that notion.
The only way we're "carnivores" (other than maybe eating bugs or worms) is with the assistance of technology (heat). Killing our fellow Earthlings and eating their bodies is about as natural for human animals as flying is...both require technological assistance to be accomplished to any meaningful degree. You can jump off a roof (unassisted by any technology) and "fly" for a short time...but the end result probably won't be enjoyable.
In the meantime, live vegan and you won't need to worry about your healthy survival being negatively impacted by your food choices...and your fellow Earthlings won't have their healthy survival negatively impacted by your food choices either. That's a win-win for everyone.
