Climate affects regional population distribution in the U.S. the same as it does everywhere. People
seek out climates they find pleasant, and in which they can feed and house themselves with
consistent security and safety. As technological advances enable mankind to overcome limitations
of climate, people move in greater numbers into what would otherwise be marginal climatic areas.
The best example of this is the invention and widespread use of air conditioning leading to much
heavier colonization of the Sun Belt.
• It is estimated that there were 33.4 million people living with
HIV/AIDS worldwide at the end of 2008. Approximately 2.7 million
people were newly infected with HIV and the AIDS virus in 2008 .
Estimates state that HIV/AIDS took the lives of more than 2 million
people in 2008.
• In 2008, around 430,000 children were born with HIV, bringing to
2.1 million the total number of children under 15 living with HIV.
• Women account for approximately 50% of people infected with HIV.
In most regions of the world, HIV is affecting women and girls in
• Young people account for around 40% of all new adult (15+) HIV
• Water shortages, soil exhaustion, loss of forests, air
and water pollution, and degradation of coastlines
afflict many areas. As the world’s population grows,
improving living standards without destroying the
environment is a global challenge.
• In India, the over population has engulfed almost all our
achievements in industrial growth, agricultural production,
supporting services like medical care, housing, transport, education,
banking etc. It has put serious pressures on every sector of our
economy and every section of society. Almost all our national
problems can be traced back to have their roots in overgrowing
• As the population rapidly grows, the more the
location will depend on money. The making of
more housing and goods required a set
amount of income, without that income the
location will suffer fatal changes such as
poverty, starvation, and less resources.
• Birth control is one way to
help prevent over
population. The more pills
the women pop, the less
babies will pop
• The Chinese people have come up with an
idea to lower population because they are
starting to experience over population. They
now have a rule that allows a couple to only
bare one child or become pregnant once. If
disobeyed, the child will be sent to a family
who has no child.
• There are many countries and continents that have very
little population rates. They should think about moving to
the more rural locations. Some of those locations my not
be suitable for a person to live, but if scientist develop new
ways to overcome those obstacles, living would become a
