Macro Events and Wealth Creation

The chart below is from a UBS/PwC report on Billionaires. 

The chart shows how macro events have shaped wealth creation. What current macro event is generating wealth now? My bet is on global warming, particularly climate engineering (clean water, clean air, etc), renewable energy (reduce global warming), and virtual reality (reduce travel/transport need).
