Question

Explain how famine, disease, and war are more likely with larger populations.

short paragraph

Answer 1

As populations grow, the strain on food, water, land and health services increases, making harvest shortfalls, supply-chain disruptions and nutritional deficits more likely and raising the risk of famine. Bigger, denser settlements and more frequent interactions speed the spread of infectious diseases and can overwhelm medical systems, while expanded agriculture and urbanization increase contact with wildlife and zoonotic spillover. Resource scarcity and large displaced or unemployed populations heighten competition and grievances, which, combined with weakened state capacity, raise the probability of violent conflict. Climate change and environmental degradation often amplify all three pathways, so larger populations tend to make famine, disease and war more likely.
