You have now reached overpopulation!
Nobody seems to want to talk about it, but we are now in deep shit.
Yes - because of overpopulation!
Just go to YouTube and search for traffic congestion ... in Los Angeles ... in the Bay Area ... in India ... in China ... in Bangkok ... in Jakarta ... in Japan ... in Mexico City ... ALL OVER THE WORLD!
Current world population is about 7.6 BILLION PEOPLE.
Here are some country populations, for comparison and contrast...
China... 1.4 BILLION
India... 1.33 BILLION
Japan... 128 MILLION
The United States... 324 MILLION
Canada... 37 MILLION
Pakistan... 194 MILLION
Russia... 144 MILLION
Italy... 60 MILLION
Denmark... 5.8 MILLION
Australia... 24 MILLION
England... 53 MILLION
Currently the "winners" of the population game are China and India, the only two countries significantly past the 1-BILLION MARK! (Reminds me of the "How Many Served" signs at McDonalds)
Furthermore, wikipedia says, "The United Nations estimates [the world population] will further increase to 11.2 billion by the year 2100."
One of the biggest concerns you should have for the future, is energy. Specifically OIL.
If you study the oil industry, you would learn about the EROEI (Energy Return on Energy Invested / also called EROI for Energy Return on Invested).
In the early 1900s, the EROEI was around 80 to 1. Meaning, it took the equivalent energy in 1 barrel of oil to extract 80 barrels of oil from the ground. So the "profit" is 79 barrels, minus the energy cost to refine and transport it.
By about 1970, the EROEI had fallen to about 30. With more exotic methods used today, such as Canadian oil sand extraction and fracking, the EROEI is more likely around 10 or less.
As a result, getting oil out of the ground is getting much more expensive. Which means, gasoline prices will be on the rise, as the barrel of oil price rises.
Long story, short... Conventional drilling on land is the easiest and least costly method. Fracking is less productive and more expensive, as fracking depletes its oil source much faster. Deep water drilling is also extremely costly. And the "oil sands" in Canada might be the dirtiest, most expensive and least productive method, in which they knock down the trees in the forest, scrape the top soil away and dig up the underlying dirt/bitumen - a mixture of viscous oily sand, clay, dirt and yuck!
The oil companies go to places like deep water in the Gulf and the oil sands of Alberta, Canada, because the easy cheap stuff has already been discovered on land, and many of the oil fields, worldwide, are depleting. In other words, many of the producing reserves have past their peak.
Funny how China has about 1.4 Billion people, which is about 4.3 times the US population, and the US uses more oil than China. But that is projected to change in the not-too-distant future. Their consumption / demand is going UP!
This all ties in to the global financial system too. As a hint of what may be in the cards... its been reported that China will want to (or demand to) pay for oil using Chinese Yuan, instead of US Dollars. Heard of the "petrodollar?" Any idea of how that could wreak havoc in our economy and on the value of the dollar itself?
As time goes on, as oil reserves deplete, as the population continues to grow, as traffic congestion spirals out of control, you've got to wonder, is it possible that demand will surpass the capabilities to extract enough oil to keep up?
Also, consider, that oil is used in the manufacturing and production of plastics, rubber, asphalt, pharmaceuticals, pesticides, fertilizers, and many, many other things we've come to depend on.
So... getting back to the population issue...
Is there enough oil for everyone? How long will the joy ride last? Can the world keep up with increasing food production? Can the miners keep up with extracting enough of the things we require, like gold, silver, phosphorus, cobalt, lithium, cerium and other chemicals and minerals?
As some point the problem of overpopulation will correct itself.
The future population decline may come as a result of one more of the following... war, nuclear conflicts, starvation, disease, lawlessness.
Perhaps the most dangerous threat to us today is the man-made EMP. That is the Electromagnetic Pulse ... an explosion or burst of electromagnetic radiation, which basically gets into the power grid and can destroy electronics, which, in the worst case scenario, could knock out most electricity in a given region, potentially for months, if not beyond a year.
You can also add natural disasters in the mix. Things like major volcanic activity or a coronal mass ejection from the sun, which could have an impact similar to that of an EMP. Or, as the dinosaurs were killed off, we could suffer a similar fate with a large-enough meteor strike.
Perhaps, in such a cataclysmic event, our politicians will be the only survivors to emerge from their government bunkers. Of course, a world with only politicians might be as bad as the cataclysm itself.
In a finite world, with finite resources, it is a certainty that human population will reverse in the future.
The big question is what will cause it? And when?
