First to argue about population increase; still influential.
Today: 1 person, 1 unit of food.
25 years: 2 p, 2 UOF.
50 years: 4 p, 3 UOF
75 years: 8 p 4 UOF
100 years: 16 p, 5 UOF
Reasons for declining birth rates
lower CBR's higher CDR's.
No one wants to increase CDR, so we decrease CBR.
two strategies successful in reducing birth rates:
1. emphasize reliance on economic development
2. emphasize reliance on distribution of contraceptives
approach to lower CBR
-women will be more informed and make better decisions about having children
-improved healthcare will help children live longer, therefore less kids are needed
comes from epidemiology, which is a branch of medical science concerned with the incidence, distribution, and control of diseases that effect large numbers of people.
Epidemiological Transition: Stage one
stage 1: pestilence and famine
Epidemiological Transition: Stage two
"Stage of receding pandemics"
disease that occurs over a wide geographic area and affects a very high portion of the population
epidemiological transition:stage 3 and 4
stage of de generative and human created diseases, characterized by decrease in deaths from infectious diseases and increase in chronic disorders associated with aging(heart attacks, cancer, cardiovascular diseases)
Epidemiological transition: Possible stage 5
stage of re-emergion of infectious and parasitic diseases
Consequences: higher CDR
Reasons for stage five.
Evolution: DDT- resistant mosquitoes equals more cases of malaria
Poverty: people won't take their medicine long enough and they spread diseases through coughing and sneezing
Improved travel: picking up diseases from where you vacation and spreading them.
some fear _____ may be responsible for spreading infectious disease
