So, it would seem that after reading this article the world should be blaming the tree huggers and PETA for global warming and not all of us little SUV drivers.
"German scientists have discovered a new source of methane, a greenhouse gas that is second only to carbon dioxide in its impact on climate change.
The culprits are plants.
They produce about 10 to 30 percent of the annual methane found in the atmosphere, according to researchers at the Max-Planck Institute for Nuclear Physics in Heidelberg, Germany.
Methane, which is produced by city rubbish dumps, coal mining, flatulent animals, rice cultivation and peat bogs, is one of the most potent greenhouse gases in terms of its ability to trap heat." (source)
So plants and cow farts are ruining the world...? Cool.
