Modern medicalCited by: 1.   Introductory guide to human population genetics and microevolutionary theory. Providing an introduction to mathematical population genetics, Human Population Genetics gives basic background on the mechanisms of human microevolution. This text combines mathematics, biology, and anthropology and is best suited for advanced undergraduate and graduate study.

From to current year: elaboration of data by United Nations, Department of Economic and Social Affairs, Population Division. World Population Prospects: The Revision. (Medium-fertility variant). Our population is expected to grow to over 9 billion by , yet the ability of our environment to provide space, food, and energy are limited. Explore population growth from 1 CE to , see how our numbers impact the environment, and learn about the key advances and events allowing our numbers to grow.

Growth of the Human Population. This graph gives an overview of human population growth si BC. It took until about AD for the number of humans to reach 1 billion. It took only a little over years for the number to reach 2 billion. The human population recently passed the 7 billion mark! But Empty Planet is not a book about statistics so much as it is about what’s driving the choices people are making during the fastest period of change in human history. Ibbitson and Bricker.

Jeffrey McKee's book, Sparing Nature: The Conflict between Human Population Growth and Earth's Biodiversity is just as applicable to the world's current environmental crisis as it was when it was first published in paperback in Through a captivating use of foreshadowing and direct and circumstantial scientific evidence, McKee weaves Reviews: 3.

The book received furious denunciations, many focused on Ehrlich’s seeming decision—emphasized by the title—to focus on human numbers as the cause of environmental problems, rather than.

The authors’ cogent analysis encompasses demographic milestones like surpassing the seven billion population mark and becoming a majority urban population for the first time in human history, as well as the repercussions of a global financial crisis and the implications of two important ongoing trends: aging and fertility decline.

Long-Term Consequences of Exponential Human Population Growth Many dire predictions have been made about the world’s population leading to a major crisis called the “population explosion.” In the book The Population Bomb, biologist Paul R.

In demographics, the world population is the total number of humans currently living, and was estimated to have reached billion people as of March It took overyears of human history for the world's population to reach 1 billion, and only years more to reach 7 billion.

The world population has experienced continuous growth following the Great Famine of – and. As human genetics and genomics research often employs tools and approaches derived from population genetics, this book helps users understand the basic principles of these tools.

In addition, studies often employ statistical approaches and analysis, so an understanding of basic statistical theory is also needed. A social science that applies the principles of population ecology to the study of statistical change in human population.

Family Planning The effort to plan the number and spacing of one's children, so as to offer parent and child the best quality of life possible. Book claims global population will start to decline in 30 years despite UN predictions - and says once it does 'it will never end' There are billion people living on Earth, expected to climb.

Ehrlich will be averted. The world population has grown tremendously over the past 2, years. Inthe world population passed the six-billion mark. By Februarythe official world population had jumped over the seven-billion mark to an estimated billion, according to Worldometers, a world statics website operated by an international team of developers, researchers, and : Matt Rosenberg.

The formula for exponential population growth is N=N 0 e rt where N 0 is the starting population, e is a logarithmic constant (), r is the rate of growth (birth rate minus death rate), and t is time.

If you plot this equation, you see a curve arching upward over time as the population increases exponentially, assuming no change in the rate. Section Human Population Growth - Patterns of Population Growth and Future Population Growth.

You have learned how birth and death rates affect population growth. The age structure of a population can also have an effect on the growth of the population. It tookyears for our human population to reach 1 billion—and only years to reach 7 billion. But growth has begun slowing, as women have fewer babies on average.Get this from a library!
