The video explores population modeling, focusing on Thomas Malthus's theories about population limits and growth. It introduces P.F. Verhulst's mathematical model, which attempts to describe population behavior more accurately. The video explains differential equations used in modeling population growth, solving them to show exponential growth patterns. It discusses the implications of such growth and introduces Verhulst's improved model, which better aligns with Malthus's ideas about natural limits.
