Person: Jeff Bezos

From when the world had just tens of millions of inhabitants to today, where it is closer to ten billion, the concern has been the same. That there are too many people for the Earth’s resources to sustain. The question becomes is there something different about this time - does climate change change the equation - or will Sir David Attenborough join Plato and Thomas Malthus as famously incorrect worriers about overpopulation?

Legend has it, a few years ago, Jeff Bezos demanded that his team at Amazon Studios create a fantasy epic that would put Game of Thrones to shame. What resulted was Wheel of Time - an incredibly expensive attempt to create the next global fantasy phenomenon.

With Jeff Bezos announcing that he would be stepping down as Amazon CEO to focus on his space efforts with Blue Origin and his charitable work with the Day One Fund, there has been a lot written about the greatest businessman of our age. As he steps down from the $1.7 trillion dollar company he started in Seattle, he finishes as the second wealthiest person in the world making $149,000 every minute from the retail and web services giant.
