   https://www.youtube.com/watch?v=sI1C9DyIi_8 some basic thinking. 
With a growth of 7% per year you double in 10 years time. 

When bacteria double in a bottle every minute and the bottle is full at 12 o'clock, start at 11 at 11.59 the bottle only will be halve full, 11.58 it will be 25%, 11.57 just 12,5% and 11.56 only 6,75%. 

The demand for oil in the US has been growing by 7% per decade most of the 20th century. Of course there is some limit ! 

With 20% of the people using almost a 100% of the production capability of this globe they also produce the poverty of the other 80%. 

When humans as a species want to survive we have to step back, start doing things more clever-and soon.
