Now it emerges that far from the attacks being random and unprovoked it was in fact we humans who started the war.
Let me tell you the story of a classic Whitehall farce, a tale of how the government came within a whisker of advocating bovine genocide.
It all began when officials at the Department of Health decided to part-fund a piece of independent research looking at how health professionals could help combat the effects of climate change.
The boffins came up with a rather courageous idea. Why not kill 30% of Britain's cows and sheep?
Sensationalist bolding is mine. This is what they call blowback and if we want to end this war we must have the courage to end the cycle of violence, we spend ten times as much on bolt guns to slaughter cows as we do on day care centres for little calves! Why wouldn't the cows attack us?
Unsurprisingly Andy Burnham, whose specialness I have often admired on this blog was at the heart of this plan.
