Methane gas released by dairy cows has caused an explosion in a cow shed in Germany. Cows each produce hundreds of litres of methane a day, and methane can have explosive potential if it reaches the right concentrations.
Kangaroos can’t fart. They convert the small quantity of methane they produce into an energy source which their body reuses. Scientists hope that they will be able to transfer the bacteria that causes this in kangaroos to cows, to reduce methane emissions to save the world from the latest fashionable catastrophe: global warming.
