Thomas Malthus

Who was Thomas Malthus?

English Economist (1766-1834)

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.
