Over the billions of years that mother Earth has been around, it would be unimaginable to think that the planet’s inhabitants regularly made each other daisy chains and held hands.

When people saw sense, removed their spears from their rivals’ intestines and vowed never to fight again, the world became a better place. But then again, these ancient fighters never had to deal with celebrity folk flinging words at each other today. In the creaking era of Britpop, it was Blur vs Oasis, and today everyone is entitled to have a pop at Kerry Katona. Some people, however, feel that arguments with humans are pointless.
