I haven't actually seen this film, however have been explained it's theories in detail.

I quite liked thinking about it as a jar.

Lets say you have 3 jars of jam in total.

Following exponential growth (lets say it doubles every day, although in reality oil production probably doubles every 7 years or so).

It might take you 50 days to use half of the 1st jar, but then will only take you another day to use the rest of the jar and how much will you use the next day? Well you'll end up with 3 empty jars.

It's obvious that exponential growth is just not sustainable.

Whilst we could possibly come up with cleaner alternatives to oil, such as the organic catalysts that they have discovered recently which can extract hydrogen from water filled with decomposing greens. It is still not sustainable, and the human population will likely have to be reduced if we are to survive.

Even colonising other planets will not help, just look at the jars…

Let's watch it!

It is perhaps the scariest film ever made.
