$this->bbcode_second_pass_quote('Narz', '')$this->bbcode_second_pass_quote('pstarr', '')$this->bbcode_second_pass_quote('davep', 'T')he question then becomes "Can we produce a given quantity of food without recourse to as much energy as we do now?" and the answer is obviously yes. So Liebig's Law is incorrectly appropriated in his argument. It's not as simple as saying that we used a phantom energy source and therefore we are in overshoot.
It is certainly not obvious we can produce our food without petroleum. On the contrary it is virtually impossible to do so. I challenge you to name one agriculture
system in the world today that is not utterly dependent on fossil fuels, primarily diesel. I will not consider exceptions such as permaculture gardens, bio-intensive communes, or science fiction hydroponic gadgets. These exist only as experiments or isolated prototypes.
It is up to you to describe a agroeconomic example, model, or theory that will feed a modern industrial society, living beyond a neolithic or paleolithic state (in a condition known as civilized) without petroleum.
Now in the absence of such example it becomes true then that Liebig's Law is in fact "
correctly appropriated," that we do use "a phantom energy source," and "therefore we are in overshoot."
by your reasoning DaveP
furthermore you ask for mathematic proof of overshoot. That is simple. The exponential growth function applied to the biologic imperative to leave more offspring then oneself.
I don't see any proof that "it's impossible to produce our food without petroleum". If we can make electric buses, we can make electric farm equipment. Organics are a huge market probably doubling every few years.
Permaculture & home gardening is small scale now because food is so incredibly cheap (why grow your own potatoes when you buy a 20 pound sack for $5.50?).
Our SUVing, road tripping, flying to Paris lifestyle will have to change, and soon. But aside from a Matt Savinar wet dream of complete collapse and anarchy, we'll have enough oil to keep our farms running and most people eating (in the 1st world anyway) for a long time.
And again, fossil fuels are not the only way to run farm machinery. And again it makes sense that backyard food production is still so rare. We're still rich as Fark relatively speaking. Maybe when people can no longer get $1 cheeseburgers & all-you-can-eat Chinese buffets for $8 & hunger is a bigger issue than obesity they'll start looking into alternatives. Shouldn't have to be that way of course but for most people it is.
