For awhile now most scientists say that methane gas is one of the primary causes of global warming. After seeing a Truth commercial on TV about smoking and methane gas, I wanted to see the type of impact cigarette smoking has on our atmosphere.
According to FSU's science department , smoking worldwide releases about 2.6 billion kilograms of carbon dioxide in the air every year. It also releases about 5.2 billion kilograms of methane every year.
So there's another reason to quit smoking, not only are you helping yourself but also the environment.
