Comment from another website: We need to put an emissions tax on any intestinal flatulence based on the decibel level of the escaping gasses! Monitoring stations could be created that would contain high amp microphones that would pinpoint any abrupt animal discharges of methane gas. NSA could oversee the technical operations and Homeland Defense could then arrest the miscreants and round up the animals. Studies have shown that most of the methane flatulence comes from Washington DC! We need to tax the government first until they cannot print anymore money and then every living thing that breaks wind.
FWIW, the dark green BBC is the least reputable reporter of anything to do with "greenhouse" gases or climate change.
