“Nobel Peace Prize Laureate, Archbishop Desmond Tutu, has called for urgent action against the threat of climate change, while speaking in Tromso, the largest city north of the Arctic Circle.”
A key point:
“The service ended in a procession to the Arctic shore, where Russian
Orthodox Archbishop Simon of Murmansk blessed the ocean.”
So the reason that there are no more vampires in the world is that the ocean has been blessed, effectively making all the water in the world holy water.
