Same lecturer as yesterday. Talking about population and consumption. Factors affecting growth rate: number of children, fertility, health, general age, education level, are of child bearing; infant mortality, life span, health care, elderly care, occupation and risk, social stability.

Population explosion
Exponential growth.
Going through a population density map of the whole world. Future scenarios. Analogy with compound interest. Another analogy with a cage of rats left to reproduce and the population exploded and the rats started killing themselves to extinction.

Improvements to human consumption. Fair share of resources. Deprecation of basic needs. Rich countries taking more than they should in terms if resources. Ecological footprint. Analogy with number of planets needed to sustain global consumption. Competition for resources.
