Crash Course: Chapter 3 - Exponential Growth by Chris Martenson

Chapter 3 (Exponential Growth): The most important Key Concept of the Crash Course, exponential growth, demonstrates how world population, oil consumption, U.S. money supply, water use, forest loss, species extinction, and fishery exploitation are rapidly reaching their natural limits. The implications for your life are powerful, and demand attention.

yea the "hockey stick" thing has to do with the order of magnitude of the y-axis. in a world of touch screens made in asia, visual stimulation is a prerequisite in order to educate first worldistan. welcome to the 21st century you gasoline burning shitheads

Population growth ...

[qwert4327able]

Population growth and viral growth in general only behaves exponentially in the short term until the limits on resources feed back on this and it eventually stabilises.

[qwert4327able]

As a maths student I have to say this is wrong. The sudden shift in the hockey shape graph is due to economic and technological development meaning that carrying capacity of the earth increasing - this is due to medicine advances etc. and being able to produce more food - this is especially true in places like india.

That said, it's true we live in crucial times, because it's true that if the rate of population growth stays the same, we will soon reach the carrying capacity of the earth. I don't see why you need to appeal to manufactured concepts like the hockey stick shape being inherent in exponential growth in order to prove this point.

[freierz]

While I agree with the ideas being presented here, I'm afraid I'm one of those 'mathematicians' who will complain about the presentation of the concept of exponential growth. There's no such thing as a "hockey stick" shape in exponential growth graphs - even if you CAN set a maximum on the dependent axis.

The fact of the matter is, population has a hockey stick shape because the rate has increased in the last couple hundred years due to medicine and the like.
