The cows and sheep and the gases

Broadcast
Last night on some BBC TV programme or other – that we happened to cross – it was announced that scientists from Aberystwyth were investigating and analysing the methane produced by cattle and sheep – so here is a little ditty:

So the cows and the sheep – awake or asleep
Emit gases which effect global warming.
And scientists from Wales – in the hills and the vales
Are studying these emissions which are harming.
They have locked up some sheep
And they’ve locked up some cows
So they can study the gas at close range.
Seems an odd sort of task – not the sort of thing you would ask
Anyone to take on who wasn’t just a little bit strange.
