Where the sparrows gone?

When I was a kid they were so well in population.When I got up in the morning, the mind would have been happy with their tweets but now they disappeared.
                                  The reason is microwave radiation of mobile towers.Mobile tower radiation clips sparrows wings.
Sparrows are effecting by the cellphone radiation.The microwave radiation of mobile towers effects on the nervous system and immune system of small animals.
                              That's why we can see these small birds rarely.Not only sparrow even so many small animals are disappeared and we don't even know about them.
