Thomas malthus
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
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


Lowering the nir
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
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
