Thomas Malthus
Who was Thomas Malthus?
English Economist (1766-1834)
Argued that population was growing too fast…food supply would not keep up!
Starvation, war, chaos!
Was Malthus right?
YEA BOI!
Neo (new)- Malthusians Rapid pop. growth in
LDC’s (due to medicine and tech)puts a strain on these countries.
Population is outstripping a variety of resources, not just food ie- oil, fresh water, arable
land
HECKY NO!
Humans are able to adapt (possibilism) and create new sources of food
GMO’s, commercial farming
Larger population = more workers/ ideas (Ester Boserup)
We have the resources, but they aren’t equally shared (Marx/Engels)
Lowering the NIR
How do we get NIR down?
Two options 1. Lower Birth Rates 2. Raise Death Rates
Let’s go with option #1, because nobody likes dying.
How do we lower birth rates?
EMPOWER WOMEN
More $$$ spent on education
Women attend school/ college
Become employed, work more, make fewer babies
Better education about reproductive health
CONTRACEPTIVES
Economic development/ education is a long term solution….what about the short term?
Distribute contraceptives widely and cheaply. Less than 25% in SS Africa Over 65% in Asia/LA
Some oppose birth control methods, primarily due to religious reasons.
