I’ve just emerged from a lengthy hibernation in the hot water cupboard (autumn is coolish round here) to find that the Googleverse is full of articles which postulate that the methane emissions of the dinosaurs 150 million years ago could have been a major cause of ancient global warming and a contributory factor in their disappearance.
Researchers at Liverpool John Moores University have set up a mathematical model which shows how much methane billions of dinosaurs would have produced during the Mesozoic era. The figures suggest that the dinosaurs by themselves may have farted and burped out more methane than the modern world produces from all sources and that is why the planet was so much warmer then.
Methane is a by product of digestion in the gut of all animals and vegetarian dinosaurs who munched on anything green and leafy were particularly prolific emitters of the gas. Far more so presumably than the meat eating Mr T Rex.
Carnivores like myself do little harm to the atmosphere in the 21st century but there is one obvious question which no-one has asked…..
Should vegetarianism be banned in order to save planet Earth?
