Are Rainforests Poisoning the Atmoshphere?

Greenhouse gas methane produced by living plants:

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.

Yet another reason not to sign the Kyoto protocol without much more scientific study.
