Oh please, don't tell me what had went on for billions of years wouldn't go on for another million....Please, prove that entropy can be reversed on any scale. It can be slowed, this is obvious. Crop rotation, which you so desperately want to be a cure all, can slow the loss of nutrients from farmland. But it does not mean that that land can support an infinite number of seasons.
Crop rotation might not be the cure all, but thats a microscopic system like mike said. The macroscopic system is that whatever we consume as farm products are still biomass, and what happens is that they usually get dumped into the sea or such to feed the alegies for nice red tides.... I guess we'll have to eat different stuff if this keeps up, but there will always be stuff to eat. Alternatively, we can just redistribute the biomass and carbon with technology and planning that is not currently beyond us.
Yeah, so the farmer can just use some fertilizer and plant some nitrogen fixing plants and wait a few years and the land would be productive again. (but which farmer is gonna do that?)
In any case, all the processes described is reversible as long as we have heat reservoirs of different temperatures to dump entropy to.
There is a upperbound on the RATE of production (proptional to energy supply), not net quantity. (for another few billion years at least)
Oh please, the earth was desert and rock before there was life.He is ignoring observation of the spread of deserts, but doesn't care.
Of course one can reverse desertification by moving water back in and slowly rebuilding the soil and climate. But we lazy humans don't care because it'd take something like a generation to make anything useful out of it, instead we perfer slash and burn farming and leave the problem to someone else.
However, unlike some nice curves in microeconomics class, the consumption of goods does NOT goto infinity if the cost is zero. (AOL CDs anyone?) Last time I checked, I'm not hoarding air because it is free. The value marginal value of an objects can and do become zero when sufficient quantities are supplied. One does not need infinite resources for zero cost goods.Allow me to explain a bit for the folks who are just joining in. Kojikun is another of those who refuse to believe that automation will not automagically cause everything to become free after some threshold. In amongst his rantings where he proves he doesn't understand the relation between cost and value, and microscopic and macroscopic, I pointed out in plain English that value, thus cost, will remain simply because there are limited resources. If you just declared them free anyone, you get a massive economic crash when you run out. Kojikun simply refuses to believe you can run out of food if you make it free to 6+billion people.
But the question is, does the world have enough resources to satistify everyone, and that is a whole other matter than playing around with arguments.
Of course, the simple solution would be to kill lots of people, which solves the problem altogether.
