8. Important Views On Population Growth
Malthusian theory:
Human populations tend to grow at an exponentential rate
where as food production tend to very slow growth.
Starvation,poverty,disease,crime and misery are expected.
For stabilizing the population growth we need
“positive checks” –famines,disease outbreak and violence
“preventive checks” –birth control systems
9. Maxian theory –karl Marx
Population growth – a symptom rather than cause of
poverty, resource depletion ,population and other
problems
Social exploitation and oppression of the less privileged
people leads to poverty,unemployment,environmental
degradation and in turn cause over population.
