This is a tale of the small village of Skafi, which is located some 500 km north of Athens. A man of German origin, who identifies himself only as Yiorgos, waters his garden in his home, carries wood and walks through the village, but without any one accompanying him. Yiorgos is the sole inhabitant of the isolated village.

There was a time when Skafi had a population of about 45 families, but today it is populated by Yiorgos alone in the winter and about a dozen elderly Greeks who come in the summer.

According to a census carried out earlier this year, population in Greece has shrunk by over 1 per cent over the last 10 years. However, as per official U.N. population projections, the world's population is projected to reach 7 billion on Oct. 31, 2011, Reuters reported.
