for the past 2 centuries the human population growth has
been exponential
every _ days the human pop increases by roughly 1.8 million and 800 people die
5 days
Earths carrying capacity for humans
we can develop technologies to help us overcome some limits
why was China’s one child policy controversial
limited individual freedom of choice

carrying capacity
Factors increasing Earths ability to support humans includes
increases in agriculture
cheap fuel sources
improved efficiency of using natural resources

which shape shows a declining growth rate
inverted pyramid
natural increase in populations is
CBR is higher than CDR
if a developing nation decreased ya growth rate to 0 then
population would level off

high avg per capita GNI
gross national index

theory of demographic transition
country moves from subsistence economy to industrialization and increased affluence undergoes predictable shift in population growth
which of these is a proper pairing of a characteristic and population growth
poor countries have high population growth rates
effects of human population tht impacts environment
population
affluence
technology
sustainable development
development that allows nature to replenish itself
sustainable carrying capacity of earth is
unknown
Thomas Malthus believed that
population growth will start war famine and disease
in 2010 the pop of earth is … with ….billion living in china
- 8
1. 3
replacement fertility
is = to 2.1 in stable populations
which is not true of Africa’s AIDS crisis
avg life expectancies have increased over the past 10 years
the current worldwide pop with an increase of 1.2 percent will double the population by
58 years
according to the demographic transition model
rapid population growth is a short term phenomenon between the drop in the death rate and birth rate in a population
