What Does Population Growth Look Like in Biology? What Are Carrying Capacities, Predation, R-Selections, K-Selections, Overshoots, and Die-Offs?

The human population has increased dramatically in the last two centuries. Since the Industrial Revolution, 200 years ago, our population has increased from around one billion to nearly eight billion. There are many reasons as to why our population is growing at such a rapid rate; this growth can be attributed to improved healthcare, industrialization, among many other factors. For humans, our growth can be measured by a theorized model of population growth known as the demographic transition model. This theory works very well for human populations, but what about the natural populations you clicked on this video to learn about? When it comes to biological population patterns, we need a whole new set of science, and a whole new set of biological terminology, to explain it. Let’s learn about population patterns in the natural world.
