Key Issue 4: Why Might Population
Increase in the Future?
• Population and Resources: Malthus argued that population
grows faster than food production, potentially leading to shortages.
Neo-Malthusians echo this, but critics suggest technological advances
and resource expansion ease the problem.
Malthusian Theory
• Argument: Malthus believed population growth would outpace
food production, leading to famine and disaster unless controlled by
moral restraint or natural causes.
• Modern Evidence: Agricultural advancements, especially in
countries like India, have outpaced population growth, challenging
Malthus’s predictions.
Debate: Can Earth’s Resources Support Our
Growing Population?
• Malthusians Say No:
• Rapid population growth in developing countries
strains resources beyond food, including water and energy.
• These pressures could lead to widespread resource
shortages.
• Critics Say Yes:
• Expanding Resources: Advances in technology increase
resource availability.
• Economic Growth: Population growth drives demand,
innovation, and job creation.
• Inequality: Poverty is more about resource
distribution than absolute scarcity.
