$this->bbcode_second_pass_quote('JudoCow09', 'P')lease explain to me how food was once unaccessible. I don't recall food ever being unacessible. If it was, then NO SPECIES would exist. We'd all be dead. Unless, of course, you're talking about 4.6 billion years ago and that we'll all die now 4.6 billion years later in a matter of decades.
And by the way, we don't know what the world population could have been without oil. We have only shortly inhabited, oh I don't know, half the planet recently. Population was growing before oil came along, It just boosted us. Just to say.
The argument being presented is that as food (energy) becomes more accessible, a population will grow, assuming there isn't something else that would limit population growth.
Prior to the advent of civlization, most humans on the planet abided by what we now call "animal ethics", "the peacekeeping law", or "the law of limited competition". Briefly, it means that a species may compete to the full extent of its abilties, but it may not exterminate its competitors, exterminate its competitors' food, or deny its competitors access to food. Nearly all species abide by this rule, and for 300,000 years Homo sapiens did, too. When all species in a community abide by this rule, they may all exist, but they are all kept in check, they are all limited.
When our civilization decided to no longer abide by this rule, it allowed our resource base (food) to increase, and our population grew much faster than it did before (not being limited by anything else, like lack of clean air, water, land, etc.)
And as for oil boosting us, you're exactly right. And when the peak has passed, oil can no longer boost us, nor even maintain us, because its supply is depleting. We must replace the lost energy from the loss of oil production, so we must get energy from somewhere else. Like solar panels, or hydroelectric dams, or nuclear plants, or algae farms. All of which require the investment of energy to develop, scale, mine, process, construct, package, distribute, install etc. But the energy needed to do all of that will be coming from a system whose available energy is declining, a system that will need all the energy it can get just to maintain what it currently has.
A constant flow of energy is needed to maintain the order of a system, whether that system is the human body, the weather, the economy, the government, the ecosystem. When the energy flow decreases, disorder increases. Any place where you would "take" energy from for an increase in solar panels, hydroelectric dams, nuclear plants, or algae farms, in a system where the energy input, in terms of oil, is already declining, will only increase the amount of disorder in the system as a whole.
If the system weren't dependent on oil, if there weren't 6.5 billion of us needing it, if we weren't so close to the peak, if it didn't take decades to build infrastructure, if we didn't have a system dependent on growth, if we weren't already experiencing global warming, if the laws of physics weren't stacked against us, and if people within this system didn't have a tendency to avoid dealing with a problem until it's right on top of them, this could be manageable. Otherwise, not so much.
