*The BBC World Service is an international broadcaster owned and operated by the BBC. It broadcasts radio news, speech and discussions in more than 40 languages to many parts of the world on analogue and digital shortwave platforms, internet streaming, podcasting, satellite, DAB, FM and MW relays. In 2015, The World Service reached an average of 210 million people a week (via TV, radio and online). In November 2016, the BBC announced that it would start broadcasting in additional languages including Amharic and Igbo, in its biggest expansion since the 1940s.

BBC World Service English maintains eight regional feeds with several programme variations, covering, respectively, East and South Africa; West and Central Africa; Europe and Middle East; Americas and Caribbean; East Asia; South Asia; Australasia; United Kingdom. There are also two separate online-only streams with one being more news-oriented, known as News Internet. The service broadcasts 24 hours a day.

By the end of the 1940s the number of broadcast languages had expanded and reception had improved, following the opening of a relay in modern-day Malaysia and of the Limassol relay in Cyprus in 1957. On 1 May 1965 the service took its current name of BBC World Service. It expanded its reach with the opening of the Ascension Island relay in 1966, serving African audiences with a stronger signal and better reception, and with the later relay on the Island of Masirah in Oman.

Ascension Island lies on a 6-mile stretch of isolated volcanic rock located in the middle of the South Atlantic Ocean, home of the BBC’s Atlantic Relay Station serving most of Africa and South America. Though running an island may not typically be what comes to mind when you think of digital media services, Ascension Island is a key component of the BBC’s critical daily radio broadcast to more than 30 million people across the service area. 

**The green sea turtle (Chelonia mydas), also known as the green turtle, black (sea) turtle or Pacific green turtle, is a species of large sea turtle of the family Cheloniidae. It is the only species in the genus Chelonia. Its range extends throughout tropical and subtropical seas around the world, with two distinct populations in the Atlantic and Pacific Oceans, but it is also found in the Indian Ocean. The common name refers to the usually green fat found beneath its carapace, not to the color of its carapace, which is olive to black.

The dorsoventrally flattened body of C. mydas is covered by a large, teardrop-shaped carapace; it has a pair of large, paddle-like flippers. It is usually lightly colored, although in the eastern Pacific populations, parts of the carapace can be almost black. Unlike other members of its family, such as the hawksbill sea turtle, C. mydas is mostly herbivorous. The adults usually inhabit shallow lagoons, feeding mostly on various species of seagrasses. The turtles bite off the tips of the blades of seagrass, which keeps the grass healthy.

Like other sea turtles, green sea turtles migrate long distances between feeding grounds and hatching beaches. Many islands worldwide are known as Turtle Island due to green sea turtles nesting on their beaches. Females crawl out on beaches, dig nests, and lay eggs during the night. Later, hatchlings emerge, and scramble into the water. Those that reach maturity may live to 80 years in the wild.

C. mydas is listed as endangered by the IUCN and CITES and is protected from exploitation in most countries. It is illegal to collect, harm, or kill them. In addition, many countries have laws and ordinances to protect nesting areas. However, turtles are still in danger due to human activity. In some countries, turtles and their eggs are still hunted for food. Pollution indirectly harms turtles at both population and individual scales. Many turtles die after being caught in fishing nets. In addition, real estate development often causes habitat loss by eliminating nesting beaches.
