Population, Sustainability, and Malthus

In which John Green teaches you about population. So, how many people can reasonably live on the Earth? Thomas Malthus got it totally wrong in the 19th century, but for some reason, he keeps coming up when we talk about population. In 1800, the human population of the Earth passed 1 billion, and Thomas Malthus posited that growth had hit its ceiling, and the population would level off and stop growing. He was totally right. Just kidding, he was totally wrong! There are like 7 billion people on the planet now! John will teach a little about how Malthus made his calculations, and explain how Malthus came up with the wrong answer. As is often the case, it has to do with making projections based on faulty assumptions. Man, people do that a lot.

This is a succinct summary of Malthusian ideas on population.  What do you think of his ideas?  Any specific parts of his theory that you agree with?  Do you disagree with some of his ideas?  What did history have to say about it?

Visualizing Regional Population Statistics

It was just over two centuries ago that the global population was 1 billion — in 1804. But better medicine and improved agriculture resulted in higher life expectancy for children, dramatically increasing the world population, especially in the West.


This is an excellent video for population and demographic units, but also for showing regional and spatial patterns within the global dataset (since terms like 'overpopulation' and 'carrying capacity' inherently have different meanings in distinct place and when analyzed at various scales). It is also a fantastic way to visualize population data and explain the ideas that are foundational for the Demographic Transition Model.

This video describes and explains how we got to a population of 7 billion people so fast

It also uses water to demonstrate it.

This is an incredibly powerful and remarkably well-done video by the Economist (see related article here) that is reminiscent of a TED-ED lesson on the importance and value of population pyramids.  This video goes nicely with this article from the World Bank entitled "The End of the Population Pyramid" which highlights the demographic changes that will be reshaping global demographics in the next 50-100 years.

Here is a quick introduction to the shifting population demographics and why there is a Declining Natural Growth Rate.


This video is a good way of introducing the topic of Cities and Countries Methods for Tackling a Declining Natural Growth Rate because it provides insight on why many locations around the world are currently experiencing a declining natural growth rate.

Gret Video, but why do you think there is such a diverse shift in population demographics?
