"The Worst Mistake in the History of the Human Race", an article by Jared Diamond says that agriculture in itself is flawed and is only used to sustain larger civilizations. He describes it in a sort of "last-resort" tone, relating the agricultural lifestyle to a quantitative existence opposite to qualitative lifestyle of our ancestors. Hunter/Gatherers were able to live well without the social burdens of laziness and political struggle over resources within that civilization. Hunter/Gatherer societies were small enough that there was very little social order, at most there was a chief or leader who was chosen based on skill, not lineage. Hunter/Gatherer societies also didn't have to deal with "dead-weight" citizens, the entire tribe worked except for the children, who learned how to hunt and gather from the elderly members of the group. It's easy to see the qualitative aspects of Hunter/Gatherer society, in these groups true communism can exist and the population remains healthy due to their varied diets and active lifestyles.
I agree with the fact that Hunter/Gatherer society lacks many of the problems that we have in our world today, the only reason why that lifestyle seems worse than agricultural lifestyles is that Hunter/Gatherers depend on the agricultural societies for invention and things like art and entertainment. Modern Hunter/Gatherer societies use guns and other modern tools to find food, things which they couldn't make on their own due to their lack of free time. Unless that group of hunters was exceptionally good they wouldn't be able to develop as fast as an agricultural society. While it isn't totally true that Hunter/Gatherers didn't invent anything (the spear, axe, bow and arrow are examples of this) they wouldn't be able to create advanced technologies at the rate we do now, and with that advanced technology they would create machines to hunt for them or breed their prey to kill it later, bringing us full circle to our flawed society.
Naturally we lived as Hunter/Gatherers, because humans are naturally omnivores so we can eat meat and vegetables, living as Hunter/Gatherers can be more efficient in terms of a varied diet. In the kids film about farming, "VVVRRROOOOOOMM!!!" the farms grew massive quantities of a couple of vegetables, whereas Hunter/Gatherers can hunt many different kinds of animals outside of just pigs, cows and chickens, and can gather many kinds of wild grasses and roots that we would just call weeds and dismiss as food. In out modern Agricultural society we use hormones and chemicals derived from these animals and plants we depend on, as Michael Pollan said in his book "The Omnivores Dilemma" "It's like eating corn with your corn". We don't see food as a once living thing anymore, we view it as a string of proteins or sugars that we break down. Using these words scientifically helps distance ourselves from the truth... what we ate was living (including vegetables) and had feelings and a personality (in the case of animals). As Hunter/Gatherers we become closer to our food and actually come to terms with the food and accept the cycle of life for what it is.
In the movie "Our Daily Bread and Butter" animals are treated horribly and given hormones to grow faster and are kept in small confined spaces. These animals don't really get a chance to live, they just sort of exist and die. Our way of killing animals makes them stressed and unhealthy, so it makes sense that as we eat them we become unhealthy. While I don't disagree with farm raised animals, I think they should be happy and have room to move and get a chance at life. If not for the moral conflict than for the health aspect, eating an animal that's naturally raised will be healthier. There's one scene in the movie where a crop duster kills a field of sunflowers to harvest the seeds, this illustrates that as we grow more and more food we have exponentially more waste. As Hunter/Gatherers we had little to no animal waste, and whatever waste we had was eaten by scavengers or composted, agricultural society encourages surplus, which encourages waste.
Sadly Hunter/Gatherer society works mainly in small scale or small divisions of a large culture as the Native Americans demonstrated. While not impossible, it's very unlikely that most people will accept an active fuller lifestyle over the luxurious lifestyle we have today. There are small pockets of Hunter/Gatherers left who have much better food cultures than we do. My investigation of Hunter/Gatherer societies has reinforced my argument of "Natural is better" animals tend to survive better when they don't actively evolve and let nature do its work. As humans who have actively interfered with our natural processes like hunting eating and mating we alter our evolution, but thats a larger discussion for another time. In short, we need to keep to our roots, while Hunter/Gatherer society isn't accepted by larger civilizations I do think it is a better way of life and should be considered as an alternative to those who hate our agricultural society.
