It is an eye opener . As he mentions, this is not historical data , this is not researched data and it is not hearsay , it is first witness account of a single persons life span . Perhaps, one of the best documentary in recent times . The numbers put forth are more than thought provoking, it is shocking . The comparison of Chernobyl disaster to what we have done to earth over one life span is a dark comparison of our dismal existance. Somewhere, one is forced to conclude that man is the biggest disaster in the evolutionary cycle and we can lead to an extinction level catastrophe , if we do not wake up to our reality. The proportion of human and livestock to feed humans vs the rest of animals is a figure which has to downright numb all your senses . Must watch and must action documentary to a less carbon footprint lifestyle.
