The Science of Overpopulation

The video discusses the rapid growth of the world's population, which has reached 7 billion. It explores historical perspectives, including Malthus's theory that population growth outpaces food production, leading to famine and conflict. The Industrial Revolution changed this dynamic by increasing food production and improving health, allowing populations to grow. However, current trends show uneven growth, with developing nations experiencing a baby boom while developed countries have lower birth rates. This growth impacts resources and the environment, raising concerns about sustainability and the future of biodiversity.
