Aerial Views Manilla Overpopulation Having about 23 millions inhabitants Manila, Capitol of the Philippines, is one of the biggest metropolitan regions on the planet.

Seen from above it gets visible how close those cottages and shanty housings are compressed against each other with their varicolored rooftops. Photographed out of a helicopter in February 2017.
