Colonizing Earth

Abstract

Currently, the human settlement of planet Earth is suboptimal, roughly covering some 15% of its surface. Remediating this problem involves several approaches. Inhospitable land areas can be "greened” by using modern technology, while the efficiency of current settlements can be improved. But humans could also take advantage of such new technologies to colonize the surface of still water bodies, underground and underwater environments. This enterprise would help us learn revolutionary new ways of providing food, light, heat and electricity to human populations, techniques that would also be applicable to other celestial bodies.

Keywords: Deserts, Green architecture, Seasteading, Settlement, Underground cities, Underwater colonies.
