This chapter summarizes the book's overall concept within a compact format wherein we have presented the succinct story of each chapter contributed to this volume. We describe the role of distinctly separate three poles and three polar regions (TPRs) in the planet's functioning as a system through various positive and negative feedback loops. Also we describe how the Earth as a system is connected through different pathways to its various spheres, such as geosphere, lithosphere, hydrosphere, atmosphere, biosphere, and the latest one, anthroposphere.
