In 2019, the global population is an astonishing 7.7 billion persons (black line, chart below) and in this year alone, earths human population will increase by about 81 million persons (blue and red columns, below).  As the chart below details, the poor nations will add 61 million while the wealthy nations will add 20 million (I'll detail these terms below).  This article will explain why despite this seemingly gargantuan population size and growth, it is the geographic and demographic distribution of that growth that deems further economic growth implausible (and more realistically ushers in the "Great Decline") while meanwhile offers great solace for those concerned about environmental and resource depletion issues.
