Greenland (both larger) are generally considered to be continental landmasses rather than islands. Three-quarters of Greenland is covered by the only permanent ice sheet outside Antarctica. With a population of about 56,480 (2013), it is the least densely populated territory in the world. About a third of the population live in Nuuk, the capital and largest city. The Arctic Umiaq Line ferry acts as a lifeline for western Greenland, connecting the various cities and settlements. Greenland has been inhabited off and on for at least the last 4,500 years by Arctic peoples whose forebears migrated there from what is now Canada.
Capital City Green Capital City Green Capital City Green is the branding of the bus service "27" Cardiff, operated by Cardiff Bus. The route runs from the city centre to the north of the city, serving the Maindy, Heath, Birchgrove and Thornhill districts. The service forms part of the wider Cardiff Bus network and is one of three services to have a unique branding, along with Baycar and Capital City Red. The upgraded service was introduced in 2007 when Cardiff Bus deployed on the route six out of 15 new Scania OmniCity vehicles which it had purchased at a cost of £2.5 million.
