So what exactly is CO2? Carbon Dioxide is composed of one Carbon atom and two Oxygen atoms Natural CO2 Emissions Man-Made CO2 EmissionsForest Fires Industrial PlantsVolcanoes Power Plants – used to create energy Vehicles (main source) 13% Aerosol Sprays, Paint, varnish, & other solvents Livestock Farming 18%
So how much Item 1950-59 1960-69 1970-79 1980-89 1990-99 2000 meat do I eat? Total 138.2 161.7 177.2 182.2 189.0 195.2 meats In 2000, Red Americans 106.7 122.34 129.5 121.8 112.4 113.5 Meats consumed anaverage 57 pounds Beef 52.8 69.2 80.9 71.7 63.2 64.4 more meat than they did annually Pork 45.4 46.9 45.0 47.7 47.6 47.7 in the 1950s.

How does CO2 affect the Ocean?Our oceans absorb almost half of all CO2 emissions and theabnormal man-made emissions are causing high levels of acidity making it hard for marine life to thrive. Slowed growth of plankton,corals, and other invertebratesHas 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 canbe used to detect thepresence of carbon dioxidebecause lime water reactswith carbon dioxide toproduce a precipitate ofcalcium carbonate:Ca(OH)2 (aq) + CO2 (g)→ CaCO3 (s) + H2O (l)•Carbon dioxide turns limewater milky
So why should Icare, it does not affect me! If we continue to pollutethe air we breathe and the oceans, we will begin to see a direct effect on human health. air pollution could causeabout 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?
