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.

Item 1950-59 1960-69 1970-79 1980-89 1990-99 2000

Total meats 138.2 161.7 177.2 182.2 189.0 195.2

Red Meats 106.7 122.34 129.5 121.8 112.4 113.5

Beef 52.8 69.2 80.9 71.7 63.2 64.4

Pork 45.4 46.9 45.0 47.7 47.6 47.7

Veal & Lamb 8.5 6.2 3.5 2.4 1.7 1.4

Poultry 20.5 28.7 35.2 46.2 61.9 66.5

Chicken 16.4 22.7 28.4 36.3 47.9 52.9

Turkey 4.1 6.0 6.8 9.9 13.9 15.2

Fish and shellfish 10.9 10.7 12.5 14.2 14.7 15.2

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
