  1. Introduction

    Episode 1

    Introduction

    Welcome to Human Carrying Capacity of the Earth! This chapter covers the question, what carrying capacity is, what sustainable is, and describes previous work with other estimates of the human carrying capacity of the Earth.

  2. Environmental Conservation

    Episode 2

    Environmental Conservation

    Explains and addresses environmental concerns, offers space colonization as the solution to conservation concerns, and keeps the focus on the limit analysis of human carrying capacity on Earth.

    Episode 9

    Heat

    Introduces thermodynamic problems for human habitats, whether to make the Earth's surface uninhabitable, outgoing longwave radiation (OLR), eliminating the greenhouse effect using sequestration, the thermal structure of the human habitat, the Earth population limit of heat, thermodynamic bottlenecks, and the conclusion.
