This document discusses human population carrying capacity and resource use. It defines key population concepts like crude birth rate, death rate, fertility rate, and doubling time. As countries develop, their population dynamics change as seen in population pyramids. Predicting population growth involves factors like the economy, status of women, and technology. The carrying capacity is the maximum population an environment can sustainably support. Malthusian theory says food supply limits growth, while Boserup argues technology increases food production. A population's ecological footprint is the land area required for its resources and waste assimilation. MEDCs have higher footprints than LEDCs. Population policies aim to lower growth through economic development, government actions, and education.
