Billions Of People, Consuming The Earths Resources?

The way to break free, is to introduce something new to the equation,
. . . that keeps getting cheaper and use's very little material.    

Example: In solar energy, we took a panel system that used
. . . a lot of steel, big gears, and bigger gearboxes, and redesigned it,
. . . by putting a $2 microprocessor in each panel,
. . . to create a self-tracking solar panel.  

This reduced the size of the components,
. . . cut the installation expense, and
. . . drove the cost of the system down, nearly in 1/2.
