$this->bbcode_second_pass_quote('Pops', '')$this->bbcode_second_pass_quote('ChilPhil1986', 'O')ff-topic: I refuse to accept that organic is an inherently less efficient method for growing food than conventional means. If people could change their diets off these silly neo-lithic diets to foods that could more readily be grown in a multilayered context, we could actually design agriculture that makes sense. Here's one example: Chestnut trees next to apple trees next to hazelnut bushes or a no-till rotational crop, next to vegetable patches.
Phil, that organic or permaculture is less efficient is self-evident, otherwise there would be no need for you to refuse to believe it. If it were more efficient don't you think farmers would have caught on by now? Or do you have better insight into farm economics?
The reason monocultures are more efficient and diversified farms are extinct is the exact same reason the local cobbler is extinct; mass production is simply more efficient. And what method caused the extinction? The whim and requirement of the consumer for the cheapest product possible.
I assume in your job you are in some way a specialist, what if I told you you should give up your cush income and become a handyman for the good of the world, would you?
That is the same argument made here time after time, if only stupid farmers would do what I say we'd all be saved.
Small-scale horticulture is more efficient than green-revolution scale monoculture as it is more intensively managed and doesn't need to leave the between-row gaps for agricultural equipment.
Concerning the reason why the green revolution gained traction, in France, for example, they pushed the green revolution in the 40s and 50s. Apparently each farmer could only feed 5 people beforehand, but that went up to about 25 rapidly. However, the number of farmers was reduced by a factor of 4, making the actual gains per unit area marginal. It just led to more people leaving the countryside and farmers getting into perpetual debt to fund their equipment as global prices decreased. And biodiversity was destroyed as hedgerows etc were destroyed to make way for bigger fields (and remember, it's the biodiversity that allows pest predators to survive and avoid pest plagues).
As I've explained before, you can get similar yields from the likes of walnuts as from annual crops, but without the hassle and energy inputs.
And even if the overall effect is a slight decrease in yields, a small adjustment in our meat-eating habits would more than address that.
