Changing Population Size: The population size is low. Birth and Death Rates: The birth rates and death rates are high as women have many children and there is a high mortality rate. Environmental Impact: Environmental impact remains low due to the small number of people. Stage 2 1900 Major Historical Changes: There is increasing food availability through agricultural expansion, which eliminates starvation and also causes the death rate to decrease. Changing Population Size: The population size is increasing. Women are still having many children. Birth and Death Rates: There are high birth rates but decreasing death rates. Environmental Impact: Environmental impact is increasing as frontier land begins to be developed. Urbanization is increasing and people are beginning to move to cities. Stage 3 1960 Changing Population Size: The population size is increasing—also known as the baby boom. Birth and Death Rates: There are lower birth rates and lower death rates. Environmental Impact: There is increasing urbanization and industrialization. Pollution and toxic chemicals cause problems with the increasing industrialization and burning of fossil fuels. Stage 4 1990 Changing Population Size: The size of population stabilizes. Birth and Death Rates: There are low birth rates and low death rates. Environmental Impact: The high standard of living causes a large carbon footprint and high levels of pollution. Environmental awareness begins, but much more needs to be done.

2. Stage Year Situation in the Country
Stage 1 1800 Major Historical Changes: The country is still
considered a colonial
settlement of England.
Changing Population Size: The population size is low.
Birth and Death Rates: The birth rates and death rates are high
as
women have many children and there is a high mortality rate.
Environmental Impact: Environmental impact remains low due
to the
small number of people.
Stage 2 1900 Major Historical Changes: There is increasing
food availability through
agricultural expansion, which eliminates starvation and also
causes the
death rate to decrease.
Changing Population Size: The population size is increasing.
Women
are still having many children.
Birth and Death Rates: There are high birth rates but decreasing
death
rates.
Environmental Impact: Environmental impact is increasing as
frontier
land begins to be developed. Urbanization is increasing and
people are
beginning to move to cities.

3. Stage 3 1960 Changing Population Size: The population size is
increasing—also
known as the baby boom.
Birth and Death Rates: There are lower birth rates and lower
death
rates.
Environmental Impact: There is increasing urbanization and
industrialization. Pollution and toxic chemicals cause problems
with the
increasing industrialization and burning of fossil fuels.
Stage 4 1990 Changing Population Size: The size of population
stabilizes.
Birth and Death Rates: There are low birth rates and low death
rates.
Environmental Impact: The high standard of living causes a
large
carbon footprint and high levels of pollution. Environmental
awareness
begins, but much more needs to be done.
