release into the atmosphere in a year. Measured in units (pounds or
tons) of carbon dioxide Can either be primary or secondary Primary:
directly caused by you. Driving a car Secondary: indirectly caused
by you Buying food not grown locally. Carbon footprint Calculate

Greenhouse Gases Greenhouse gases greatly affect the
temperature of the Earth; without them, Earth's surface would
average about 60 degrees colder. Since 1750 (regarded as the
beginning of the Industrial Revolution) burning fossil fuels has
lead to an increase of carbon dioxide by 40%.
Slide 4
List of Greenhouse Gases 1.Water Vapor- -most powerful 2.Carbon
dioxide- -burning fossil fuels 3.Methane- produced by decay of
organic material in landfills, enteric fermentation in the
digestive tracts of hooved animals such as cattle, goats, and sheep
(feces) 4.Nitrous Oxide- -produced by fertilizer use. Nitrous oxide
is produced naturally in the soil during the microbial processes.
Fertilizers speed up this process.
