Snails emit laughing gas

A recent proposal from the Danish Tax Commission unsuccessfully proposed imposing a flatulence tax on ruminants because of their greenhouse gas emissions. That proposal was not part of the final tax reform agreement announced on Sunday.

Now, new Danish scientific research shows that small animals such as snails, worms, larvae and crustaceans emit large and worrying amounts of nitrous oxide – also known as laughing gas – into the atmosphere.
