So what exactly is CO2?
Carbon Dioxide is composed of one Carbon atom and two Oxygen atoms
Natural CO2 Emissions Man-Made CO2 Emissions
Forest Fires Industrial Plants
Volcanoes Power Plants – used to create energy
Vehicles (main source) 13%
Aerosol Sprays, Paint, varnish, & other solvents
Livestock Farming 18%
So how much meat do I
eat?
In 2000, Americans
consumed an average 57 pounds
more meat than they did annually
in the 1950s.
Fertilizer runoff and nitrogen from
fossil fuels are increasing the severity and
duration of coastal hypoxia, or
decreased oxygen.

How does CO2 affect the Ocean?
Our oceans absorb almost half of all CO2 emissions and the
abnormal man-made emissions are causing high levels of acidity making it hard for
marine life to thrive.
Slowed growth of plankton, corals, and other invertebrates
Has led to high levels of anoxia in our oceans, the Gulf of Mexico being the second
highest anoxic ocean in the world
How is CO2 detected in H2O?
In chemistry, limewater can be used to detect the presence of carbon dioxide because lime water reacts with carbon dioxide to produce a precipitate of calcium carbonate:
Ca(OH)2 (aq) + CO2 (g) → CaCO3 (s) + H2O (l)
•Carbon dioxide turns lime water milky
So why should I care, it does not
affect me!If we continue to pollute
the air we breathe and the oceans, we will begin to
see a direct effect on human health.
air pollution could cause about a thousand additional
deaths and many more cases of respiratory illness and asthma in the United
States.
How can we preserve our oceans for future generations?
Reduce CO2!
Get a fuel efficient vehicle
Eat less meat
Paint a rooftop white
How would something so simple help reduce CO2 levels?
Plant a tree
Reduce, Reuse, RecycleVolunteer at your local recycling center
