Discussion question All I ask for is a simple paragraph answering and some simple response to both the entries .

Greenhouse gases are necessary for life on earth?but too much of a good thing is too
much. Each of us plays in a role in the release of extra greenhouse gases into the atmosphere.
The US Environmental Protection Agency has developed a way that individual can determine
his or her level of greenhouse emissions.
Go the website included under lesson resources: (Greenhouse Calculator:
epa.gov/climatechange/emissions/ind_calculator.html)
Fill out the electronic questionnaire. Report your results to people in your discussion
group. Compare and contrast results. Each student should discuss how he or she has chosen
to reduce the release of personal greenhouse gases

My current household carbon footprint is 22,904. The new total after my planned
actions is 22,624. The U.S average is 43,101. The best way to reduce greenhouse
gases is to recycle household incenitives like plastic, newspapers, and aluminum.
Recycling these items will reduce the amount of waste in the enviorment. Decreasing
the amount of pollution from vechicles and factories will also aviod extra greenhouses
gases entering the atmosphere.

Carbon Footprint
COL LA PSE

The carbon footprint number I received was 64,989. My house has a large number of
people in it and the national average for a family of my size was 74,000. There are
many ways that we could reduce our carbon footprint. We could turn off all lights when
a room is not in use, turn all things that use electricity off when we leave the house,
take shorter showers, reduce the use of the a/c or heat, put more clothes together
when we wash clothes, and perform maintenance on our vehicles more often.

It's ridiculious how much we hurt the enviorment without even realizing it. I read my
local news paper and not ,much around here is like urgent or striking enviormental
news. I have noticed lately though that it is warmer than usual this year in december
sometimes and it's nice but then again I'm like wow…ok..this is global warming, this is
so bad. Other than that my town isnt super bad and its not big on alot of factories with
alot of pollutanta, etc. so not much here. I did think of some ways to make the
envioment a better place. One easy way is simply by recycling. You can do so much by
doing something that simple. Another nice way would be buying a car such as a prius
that is super good for the envioment. I mean IF you can affor something like that. Not
everyone is made of money haha. Thoise are just some examples out of many though.
A Safer Enviroment
COL LA PSE

I'm actually more close to Atlanta, and I've read up on how the residences of Atlanta
don't take the enviroment seriously. The enviroment issues in Atlanta (Georgia) have a
high rate of excessive use of harmful releases to the enviroment such as: water, land,
and air. It states that in Atlanta region, we use up to 53% of the water and will shortly
run out in the year of 2030. Atlanta residents spend on average 31 minutes per day in
their cars, contributing significantly to greenhouses gas emissions. The air pollution is
particular in Metro Atlanta due to high traffic volumes and the proximity of urban
residential areas to commercial and industrial activities. My opinion to things that are
going on in my community, is to start bring awareness to the residences in my
community. Even start a movemen, just to start helping the enviroment organization
focus on the preservation and protection of the enviroment.

1.

The drawings below represent eclipses. Label each one as either a lunar eclipse or a solar eclipse, and

solar eclipses do not occur each month.

3. The hypothetical island country of Gilder lies in the Mediterranean Sea off the coast of
France. Demographers have studied Gilder for the past 50 years. At the beginning of the
study, Gilder had a population of 20 million. The demographers have measured birth and
death numbers, as well as immigration and emigration numbers, as shown in the data table.

Score

From the data,
a.

Calculate the population of Gilder for each 10-year period by filling in the Population (NO) and
Population (Nt) columns in the data table. Use this formula to do your calculations:
