Population and Growth
Overpopulation: Proponents and CriticsSlide2
Idea: late 1700’s
During this time (before the industrial revolution) he predicted that the growing population would eclipse the available food supply.
Created a relationship between population growth and available agriculture.
People grow exponentially while agriculture can only grow linearly.Slide3
Linear Growth: growth that occurs evenly across each unit of time.
Village of 100 @ linear growth
Each year the village would grow by 10.
Year 1: 110
Year 2: 120
Year 3: 130
After 10 years the village would have doubled to 200Slide4
Exponential Growth: the growth of a population as a percent of the total population.
Village of 100 @ exponential growth
Year 1: 100
Year 2: 110
Year 3: 121
After 10 years the village would have more than doubled to 234Slide5
Population growth could only be curbed through catastrophic events.
Population would eventually surpass available food resources which would cause mass starvation and create in of itself a growth barrier.
Malthus at the time could not have for seen the future of food production which would mechanize agricultural production and eventually the scientific food revolution.Slide6
Fear. Malthus theory could not have predicted the medical revolution (in
) which muted death rates, increasing NIR without creating wealth thus creating an environment ripe for conflict.
This creates large gaps between population and available resources.
which lack wealth are seeing the most growth. Increasing the numbers of those ‘without’ to historic highsSlide7
Population growth is outpacing economic growth (which is happening) but all resources are dedicated to the growing population rather than the economy.
This is creating developmental decline.
Belief that when there are no majority groups, minority groups compete to become majority. Contributing to growth.
Feel that this is applicable to
as well has some groups see TRF decline
He was unable to predict that in fact a larger population would actually increase production, innovation and technology.
Unjust social issues such as poverty and starvation are not a product of population growth but rather a product of unjust social and economic development
It can be argued that increased population creates power—in turn creating an economic foothold.Slide9
Theory vs Reality
In general his theory was flawed.
Food production has grown faster that the NIR since the 1950’s
While population growth (in
) has declined.
Starvation in the world does exist but not because of the lack of food but the distribution of it.
