If birds blew up when they flew into windows...

Instead of a gentle chriping and pale blue sky, we would wake up to fireworks in the sky and enormous vibrations. If birds blew up as the flew into windows,the world could be a better place. Hell, we could be safer from terrorists as we would develop metals that the birds could not erupt. But then again, I suppose, those who wish to inflict evil on the world would find a way to create stronger and more deadly weapons. An entirely different reality would emit as the sweet tweets of birds turn into battle cries and horror. Perhaps the birds would be used as weapons themselves. Ostriches would be bred and forced to run straight into walls, canaries would be sent as gifts in delicate cages only to detonate in the arms of a hopeful child. Guts and gore would cover the city as feathers rained down from the sky and the ashes fluttered off the ground.
