Abstract
External costs consist in problems of environment, health, poverty, and security. Reduction of the global unemployment ratio necessitates building innovation cycles of global external-cost internalization to evolve division of labor. In the case that there is a certain degree of demand for goods or services produced by niche industries to internalize external costs in rather sparse-populated regions than megalopolises, compensation for insufficiency of population density necessitates innovation to reduce transport costs drastically within each region, assuming another innovation to manage such large-scale waste-heat caused by transport increase as heat-island phenomena. External-cost internalization necessitates global regulations against "actio de in rem verso," so that insufficiently responsible people may not cause external costs.
