India and United States may differ in demographics, etc. but the
growing populations both result in similar environmental impacts.

lack of resources and financial stability to support such an
increase. This is worrisome due to the lack of resources and

steady deforestation rate of 0.0294 million. India The forest area
started at ~67 million hectares, and continued at a steady
deforestation rate of 0.0294 million. United States There is a
clear exponential decrease in the forest area, leading to its

actions not taken. United States There is a clear exponential

[Excel] Model Comparing population growth of India and United
States influencing forest area India, although with a higher
population than the United States shows a steady decrease in its
forest area, whereas the United States has an extensive decrease
due to its high immigration rates and urbanization, demanding more
paved areas than India. India, although with a higher population
than the United States shows a steady decrease in its forest area,
whereas the United States has an extensive decrease due to its high
immigration rates and urbanization, demanding more paved areas than
India. Growing population puts pressure on forest areas because of
urbanization and higher demands for wooden products. Growing

[General] Conclusions Our models show that there are negative
environmental impact related to population growth both in developed
and underdeveloped countries. Our models show that there are
negative environmental impact related to population growth both in
developed and underdeveloped countries. For every scenario, there
were increases in deforestation rate and water usage For every
scenario, there were increases in deforestation rate and water
usage Although the reasons for the growth differed, the results
were similar Although the reasons for the growth differed, the
results were similar Taken From:

[Impli]cations What Ifs What Ifs If we increase the number of
people educated, then the birth rate would go down, resulting in a
lower deforestation rate.If we increase the number of people
educated, then the birth rate would go down, resulting in a lower
deforestation rate. Decreasing the forest area will prevent natural
processes from occurring (photosynthesis, nitrogen cycle) and
increase global warming, natural disasters, damage to ecosystems,
loss of animal life. Decreasing the forest area will prevent

and increase global warming, natural disasters, damage to

fact bring down the population due to decreasing food sources.

Take Home Message Because this is an inevitable problem we must
raise peoples awareness and environmental stewardship to lessen the
effects of overpopulation. Because this is an inevitable problem we
must raise peoples awareness and environmental stewardship to
lessen the effects of overpopulation. Focus on the present, but
have in mind the future, thus we must start changing our actions
