Plants as possible methane source

Another classic example showing how knowledge is constantly evolving and how new findings may change what we know about nature. Now plants, often hailed as a candidate carbon sink, and a possible solution to control carbon dioxide levels, could be a source of methane gas. in fact, studies done by Frank Keppler of the Max Planck Institute in Heidelberg, Germany estimated that 10 to 30 percent of the world's methane emissions could come from plants. This finding, if verified, could mean a re-assessment of using plants as a carbon sink.
