Population & Food: Crash Course Geography #16

Today we’re going to talk about the link between population and food energy. As the world’s population keeps growing, finding ways to provide enough food and water for everyone while supporting a sustainable environment can be tricky! We’ll take a closer look at food chains and how energy is transferred between different trophic levels, follow the trends in human consumption as incomes rise, and talk about the two types of overpopulation as they’re related to the planet’s carrying capacity.
