  7. 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!

  8. Was Malthus right? Yea boi! 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) • 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

  9. 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.

  10. How do we lower birth rates? Empower Women 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. • More $$$ spent on education • Women attend school/ college • Become employed, work more, make fewer babies • Better education about reproductive health

  11. Birth Control in South Africa and India
