I just watched a program from that series, narrated by Richard Attenborough. It struck me as significant when he mentioned the Worlds population being 6 Billion people. Wow! The population of the planet has already increase 25% since that program was recorded. That is more people in the increase than the planet had 60 years ago. Perhaps this age should be known as the quickening. http://www.theworldcounts.com/count...ts_and_statistics/world_population_clock_live
