1. Global Warming Cause: Carbon dioxide emissions from fossil fuel burning power plants
Our ever increasing addiction to electricity from coal burning power plants releases enormous amounts of carbon dioxide into the atmosphere. 40% of U.S. CO2 emissions come from electricity production, and burning coal accounts for 93% of emissions from the electric utility industry [EPA, pg. 10]. Every day, more electric gadgets flood the market, and without widespread alternative energy sources, we are highly dependent on burning coal for our personal and commercial electrical supply.

2. Global Warming Cause: Carbon dioxide emissions from burning gasoline for transportation
Our modern car culture and appetite for globally sourced goods is responsible for about 33% of emissions in the U.S. [EPA pg. 8] With our population growing at an alarming rate, the demand for more cars and consumer goods means that we are increasing the use of fossil fuels for transportation and manufacturing. Our consumption is outpacing our discoveries of ways to mitigate the effects, with no end in sight to our massive consumer culture.

3. Global Warming Cause: Methane emissions from animals, agriculture such as rice paddies, and from Arctic seabeds
Methane is another extremely potent greenhouse gas, ranking right behind CO2. When organic matter is broken down by bacteria under oxygen-starved conditions (anaerobic decomposition) as in rice paddies, methane is produced. The process also takes place in the intestines of herbivorous animals, and with the increase in the amount of concentrated livestock production, the levels of methane released into the atmosphere is
