Background
This English economist proposed the Malthusian Theory in 1798.
Who is Thomas Malthus?
Population grows at this rate according to Malthus.
What is exponential growth?
The maximum population an environment can support.
What is carrying capacity?
One major factor Malthus did not fully account for.
What is technological advancement?
This theory expands Malthus’ ideas to include water, energy, and the environment.
What is Neomalthusian Theory?
The historical period during which Malthus lived and worked.
What is the Industrial Revolution?
Food production grows at this rate in Malthus’ model.
What is arithmetic growth?
Growth that multiplies over time rather than adding steadily.
What is exponential growth?
Agricultural innovations like fertilizers and irrigation challenge Malthus because they do this.
What is increase food production?
A modern concern that keeps Malthus’ ideas relevant today.
What is sustainability?
Malthus believed population growth would eventually exceed this.
What is Earth’s food supply/resources?
According to Malthus, what happens when population exceeds food supply?
What are famine, war, and disease?
Growth that increases by a fixed amount over time.
What is arithmetic growth?
In many countries, population growth slowed due to education and access to contraception.
What are declining birth rates?
One way humans have adapted that Malthus did not predict.
What are global trade, markets, or social policies?
The idea that the Earth can only support a limited population.
What is carrying capacity?
The core claim of the Malthusian Theory.
What is that population growth will outpace food production?
A modern theory that updates Malthus’ ideas for today’s world.
What is Neomalthusian Theory?
Some argue hunger exists not because of scarcity, but because of this.
What is unequal distribution of resources?
The central question still debated today.
What is whether Earth’s resources can support future populations?
How did the Industrial Revolution influence Thomas Malthus’s ideas?
Rapid population growth and limited food production.
Why did Malthus think population growth would outpace food supply?
Population grows exponentially while food grows arithmetically.
What happens when carrying capacity is exceeded?
Resource shortages, famine, and disease.
Which criticism most weakens Malthus’ theory?
Technological advances in food production.
How does Neomalthusian Theory update Malthus’ ideas?
It includes modern resource limits and sustainability.
