I only watched half way through, and what I got from that is what I always say.
There is enough resources in the world for everyone!
Apparently the population of the world could fit into greater Los Angeles standing shoulder to shoulder, it used to be they could fit on the Isle of Wight.

We live in a throw away society fuelled on the most part by greed and not need!
