Task one: Describe in detail the problem your team selected and
explain why it is important for your team to investigate the problem.
Our team’s problem relates to deforestation and the Greenhouse
Effect . The problem is that human added Greenhouse Gases are
being released, and because trees help purify the air the gases
are escaping into the atmosphere, adding to global warming. The
Greenhouse Effect is that certain chemicals in the air, mainly
carbon dioxide (Nave 2007)
, trap heat in the earth, allowing it
to stay warm. Without the Greenhouse Effect, the earth would be about 60F cooler
. Greenhouse Gases
are good, but too many can be harmful to the environment and
life on earth. Human’s actions through factories and landfills,
fertilizers, and fossil fuel production add a extra Greenhouse
Effect, that is contributing to global warming (EDF,1997) .
Humans burn fossil fuels like coal, oil, and natural gases
, with the carbon in the fuel, combined with carbon
dioxide, produce methane gas. In addition, many industrial
companies are creating the extra greenhouse gases by releasing
chlorofluorocarbons (CFCs), a chemical known to act as a
greenhouse gases. The most common activity that human use to
destroying trees for gazing land in the poor countries. Trees
help clean the air, and since we destroyed so many trees, our
environment has become more polluted, and there is less carbon
dioxide uptake by the trees. The earth will become hotter every
day, and cause many harmful effects in the future. Lately, there
are so many people want more cars, heat air, air condition
increasing the carbon dioxide every day. If no one is going to
stop, our atmosphere could be in danger,the earth will be dying under those harmful gases.
Task two: Describe how your team decided on the problem you are investigating
and explain what steps you took to narrow the focus of your investigation.
All the members of my team know, and are concerned about the
environment, and more specifically pollution and it’s effect on
the environment. We made a list of a bunch of possible things
causing pollution, and narrowed that down to only a few
problems. We talked about it, and did a little research on
pollution, and we realized that Global Warming is a major
problem. After discussing it, we decided on that as our problem.
Task three: Locate and document (using facts and figures) and describe how
:two geographic sites or two population groups have been affected by the problem your
team identified.AND two organizations, educational institutions or research
facilities are doing significant research to solve the problem your team identified.
In 1980, Cubatao, Brazil was the country with the most
greenhouse effect in the world. The air pollution was killing
all the trees in the forest. At that time, Cubatao had many industrial factories that produced smoke and flames 24 hours a
day. In late 1970s, scientist discovered that some babies were
born mentally handicapped or with some brain defect, and they
think that the main cause could have been the pollution. Some
people who were affected were diagnosed with bladder cancer, and
asthma. In Cubatao, they burned garbage containing large amounts
of CO2 and air pollutants that made breathing hard. (Milliken, M. M., 2000)
The United States of America is the leading country in producing
carbon dioxide. That is because we’re the largest consumer of
energy and electricity. The United States is also the biggest
contributors to global CO2 emission. In 1997 the total fossil of
CO2 production by the US was about 23.8%. (EPA, 2000)
The United Nations made the UNFCCC (United Nations Framework
Convention on Climate Change). They created the Kyoto protocol,
which makes rules to help decide emissions and national targets
for anyone who has signed it. Australia’s government- Department
for Environment and Heritage signed and approved the UNFCCC.
Although they haven’t officially ratified the Kyoto Protocol,
they have decided to attempt the Kyoto Target, which will help
them .(What is Australia DOing about Greenhouse and CLimate Change ?, 2006)
EPA stands for Environmental Protection Agency. It was formed in
1970 and assigned to protect, clean, and find the solution that
would decrease the amount of air pollutions in our environment.
There are about 18,000 people in America that work for the EPA.
Most of their staff are highly educated and about of them are
scientists,engineers, and policy analysts They are trying to
give the accurate information about global warming, and the
issue of climate change that would help and be meaningful to the
nations. They‘re also trying to engage the sector, states,
localities, and to focus on the challenges of global warming due
to greenhouse gases. They mainly focus on the actions and
activities which should be supported by the nations to help stop
global warming.(EPA, 2000)
Task four: Document (using two different sources based on facts and figures)
what effect this problem has on people's lives.
Global warming may not have a huge effect on us now, but in the
long run it will have some major consequences. The human-created
Greenhouse Effect is making the world’s temperature increase,
and the more we add greenhouse gases, the faster the earth will
get hotter. Eventually, polar
caps could melt, which would cause flooding in low countries and
making weather more intense, meaning more natural disasters.
Also, if they melt, even more Greenhouse chemicals will be
released into the environment, further intensifying the problem
(Bonthun, 1999) . The polar caps melting could put farmers
out of their jobs, could further lessen the food supply in
already poor countries, and make people lose their homes. More
natural disasters would mean more people out of their homes, and
more destruction to people’s possessions and land.
Task five: Document (using two different sources based on facts and
figures) the impact the problem has on the economy of our nation or on
The problem of Polar Caps melting and flooding low countries
would greatly hurt their economy, since they would get partially
or even fully flooded. That would mean more people wouldn’t have
homes, furthering the hunger issues in less-fortunate countries.
Many farmers may not be able to raise their crops and the prices
could increase rapidly. The Caps melting would also cause more
natural disaster, which means more money needed to fix up the
destruction. The Artic Ice Caps
melting will intensify the effect, adding water vapor and other
chemicals into the air (Bonthun, 1999) . Water vapor also
helps contribute to the Greenhouse Effect, so that would even
further intensify it, making Global Warming act faster, and
causing countries to have to fund research for saving their
places from eventually becoming too hot for humans to live
(Berger, W.H., 2002). In the summer, many household will
probably use more air conditioning that will waste the world
(Union for Jobs and the Environment, 2002). Also, the
increased fuel use is not only harming the environment, but also
the prices are going up for gas every day, which doesn’t help our economy at all.
