Yeah, that'S typical again! Pigeons are at fault when everything'S going wrong but the pollution that's caused by the industry in the lagoon of Venice is doing no damage? Wonderful how things in this world can be twisted again. The poop of pigeons is acid? What a ridiculous statement. These people do know nothing about pigeons. I hope they get a whole pile of poop on their heads!Maybe that's clearing off the poop IN their heads....
