In this latest volume in the acclaimed Changing Earth series, John Erickson tackles the sticky issue of human impact on the environment, likening the effects of population growth to a volcanic eruption - quick, far-reaching, human population of earth and incredibly powerful. Beginning with the origins human population of earth and evolution of Homo sapiens, Erickson traces humankind's tremendous expansion human population of earth and the subsequent strains placed on the environment. Chapters examine global pollution, resource depletion, climatic change, agricultural "carrying capacity", habitat destruction, human population of earth and the recurring problem of overcrowding. Along the way, Erickson weaves in a discussion of the Earth's necessary - human population of earth and fragile - natural cycles, human population of earth and how these are affected by human tinkering, as well as an overview of the five major historic extinctions, touching upon present-day disappearances in the biosphere human population of earth and focusing on the likelihood of a modern mass extinction. Recommendations for offsetting the already tremendous damage are provided, too. Like earlier volumes in the series, The Human Volcano is amply illustrated human population of earth and supported by an extensive glossary human population of earth and chapter-by-chapter bibliography.

Population Media Center - The Population Media Center (PMC) is an organization whose aim is to improve the health and well being of people using entertainment-education strategies, such as drama on radio and television. PMC collaborates with mass media and other organizations to: "(1) bring about stabilization of human population numbers at a level that can be sustained by the world's natural resources and to (2) lessen the harmful impact of humanity on the earth's environment".

Geodemography - Geodemography is the study of populations in their environments. It links the sciences of demography, the study of human population dynamics, and geography, the study of the locational and spatial variation of both physical and human phenomena on Earth.

Overpopulation - Overpopulation occurs when the population of a living species exceeds the carrying capacity of its ecological niche. In common parlance, the term usually refers to the relationship between the human population and its environment (the planet Earth).

Sci-fi conflict casualties - Conflict casualties occur in great numbers in many science-fiction books, films and comics - often at higher rates than in real-life conflicts and sometimes higher than the current human population of the Earth. Such high figures can be seen in part as a reaction to the much higher population growth that occurred throughout the twentieth century, though ideas of one-upmanship among authors cannot be discounted either.
