The Independent reports people have always been suspicious and fearful of bats so we needed little encouragement to point the finger their way. Some media outlets have even called for a global genocide of all bats. Of course, all this recrimination is a defence mechanism that stops us having to look closer to home.   It’s a shame we’re so quick to judge because bats are wonderful, fascinating creatures. They have been on Earth for more than 50 million years – far longer than humans – and there are more than 1,400 different species of them, meaning around 20 per cent of the world’s mammal species are bats.
