How do the environmental impacts of a growing population of a developed country, the United States, compares to the undeveloped country of India?By: Leonardo Caion-Demaestri Zo FreedbergTaken from: http://www.claybennett.com/pages/divide.html
[Intro]duction
Our world population is rapidly growing. Today: Over 6 billion people and on the rise Today: Increased immigration / lack of migration (urbanization) Lack of education and contraceptive use Medical advancements Leads to environmental and social impacts. Deforestation Global Warming Natural disasters, sea level rising Lack of natural resources Lack of freshwater Pollution Diseases India and United States may differ in demographics, etc. but the growing populations both result in similar environmental impacts.
[H]ypothesis
We predict that a growing population will cause: Higher rate of deforestation Greater loss of freshwater resources More pollution Increased global warming Strains of natural resources Social issues The differing nations will compare in that the trends will be the same, rates will differ.
[M]ethods
We first searched to find what causes a growing population. We then looked to see the effects of the growing population on the environment. Stella and Excel were used to display the impacts of the population growth on:
Forest Area Fresh Water Availability
We also compared the two different growing populations.

Population of India and US with no external pressures
India is increasing at a faster rate than U.S. U.S. This is worrisome due to the lack of resources and financial stability to support such an increase. We only chose to model birth and death rate, but there are other limiting factors that encompass each, however they were not imperative to include in this research.

Population growth influencing water availability. availability.
Water availability decreases because there is not enough fresh water available due to the increasing demand. US per capita: 6932 m^3 capita: India per capita: 1211 m^3 capita: US consumes more water at a faster rate due to its higher surface area and easier access to clean water, whereas India does not. USs USs financial status permits usage of high-end technology to purify highwater.

Population growth influencing forest area
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 possible crash, which can result in major ecosystem changes if actions not taken.

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.

[General] Conclusions
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 Although the reasons for the growth differed, the results were similar

[Impli]cations
What Ifs If we increase the number of people educated, then the birth rate would go down, resulting in a lower deforestation rate. 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 water resources may in fact bring down the population due to decreasing food sources.
[Sol]utions
Increase education programs Later marriages Contraceptive use Less of a need for urbanization (jobs) Be energy efficient (wind/ solar) Organic farming Sustainable development (build vertically) Plant more trees! Have better governmental regulations for an improved economy
Take Home Message
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 now to foresee the future we want!
