Exponential Growth – Thomas Malthus

Thomas Malthus wrote a book in 1798, the book explained how if humans had an unlimited amount of resources their population would continue to grow exponentially. But, as their resources decrease, so does their population. As shown below in the graphs, with unlimited resources a “J-shaped” graph is created where the population continues to grow over time. Then, when there is limited amount of resources a “S-shaped” graph is created where the population continues to grow but not as fast as before, then when the population reaches its cap, or runs out of resources for the “new people”, the population starts to level off or plateau.
