Question: What is the english name of the encyclical which was written by the Bishop of Rome and the sovereign of Vatican City?
Context: The Fundamental Law of Vatican City State, promulgated by Pope John Paul II on 26 November 2000, is the main governing document of the Vatican's civil entities.  It obtained the force of law of 22 February 2001, Feast of the Chair of St. Peter, Apostle, and replaced in its entirety law N. I (the Fundamental Law of Vatican City of 7 June 1929).  All the norms in force in Vatican City State which were not in agreement with the new Law were abrogated and the original of the Fundamental Law, bearing the Seal of Vatican City State, was deposited in the Archive of the Laws of Vatican City State and the corresponding text was published in the Supplement to the Acta Apostolicae Sedis.  The law consists of 20 Articles. Vatican City ( ; Italian: "Città del Vaticano" ] ; Latin: "Civitas Vaticana" ), officially Vatican City State or the State of Vatican City (Italian: "Stato della Città del Vaticano" ; Latin: "Status Civitatis Vaticanae" ), is a country located within the city of Rome.  With an area of approximately 44 hectares (110 acres), and a population of 1,000, it is the smallest country in the world by both area and population.  However, formally it is not sovereign, with sovereignty being held by the Holy See. The legal code regarding homosexuality in the Vatican City is based on the Italian penal code of 1929, the time of the founding of the sovereign state of the Vatican City.  From 1929 to 2008, the Vatican City automatically adopted most Italian laws; however, it was announced in late 2008 that the Vatican would no longer automatically adopt new Italian laws as its own. The Diocese of Rome (Latin: "Dioecesis Urbis seu Romana" , Italian: "Diocesi di Roma" ) is a diocese of the Catholic Church in Rome.  The Bishop of Rome is the Pope, the Supreme Pontiff and head of the Catholic Church.  As the Holy See, the papacy is a sovereign entity with diplomatic relations, and civil jurisdiction over the Vatican City State located geographically within Rome.  The Diocese of Rome is the metropolitan diocese of the Province of Rome, an ecclesiastical province in Italy.  The Catholic Church teaches that the first Bishop of Rome was Saint Peter in the first century.  The incumbent since 13 March 2013 is Pope Francis. This page lists diplomatic missions accredited to the Holy See, the government of the Catholic Church and the temporal ruler of the Vatican City.  82 countries currently maintain embassies to the Holy See.  The Vatican City State, over which the Holy See is sovereign, is the smallest independent entity in the world and its size renders any resident diplomatic community impractical.  Therefore, all embassies to the Holy See are located in Rome making Vatican City one of only two sovereign states, the other being Liechtenstein, with no resident embassies located within its territory.  This leads to the unique situation that the Embassy of Italy to the Holy See is based on its home territory.  This also means that an embassy of the Republic of China (more commonly known as Taiwan) to the Holy See is located in Italy, which does not recognize the Republic of China. The Church of Saint Anne in the Vatican (Italian: "Sant'Anna in Vaticano" ), known as "Sant'Anna de' Parafrenieri " (English: Saint Anne of the Grooms ), is a Roman Catholic parish church dedicated to Saint Anne in Vatican City.  The church is the parish church of the State of Vatican City and is placed under the jurisdiction of the Vicariate of the Vatican City and is located beside the Porta Sant'Anna (Saint Anne's Gate), an international border crossing between Vatican City State and Italy. Pope Francis (Latin: "Franciscus" ; Italian: "Francesco" ; Spanish: "Francisco" ; born Jorge Mario Bergoglio; 17 December 1936) is the 266th and current Pope of the Catholic Church, a title he holds "ex officio" as Bishop of Rome, and sovereign of Vatican City.  He chose Francis as his papal name in honor of Saint Francis of Assisi.  Francis is the first Jesuit pope, the first from the Americas, the first from the Southern Hemisphere, the first to choose a name not used by a predecessor since Lando in 913 AD, and the first pope from outside Europe since the Syrian Gregory III, who reigned in the 8th century. Laudato si' (Medieval Central Italian for "Praise be to you") is the second encyclical of Pope Francis.  The encyclical has the subtitle "On Care For Our Common Home".  In it, the Pope critiques consumerism and irresponsible development, laments environmental degradation and global warming, and calls all people of the world to take "swift and unified global action". The Vatican City Championship (Italian: "Campionato della Citta Vaticano" ) is the top men's association football league of Vatican City.  Founded in 1972 as the Coppa Amicizia, teams are composed of workers representing various state departments.  Teams are permitted to field an outside player from Italian amateur teams to play as goalkeeper.  The league's best players are combined to form the Vatican City national team for rare friendly matches.  The Vatican football association, Federazione Vaticanese Giuoco Calcio, is not a member of FIFA and is overseen by its president Domenico Ruggerio as of May 2014.  All matches are played at the Associazione Sportivo La Salle complex in Western Rome, although the larger Campo Cardinale Francis Joseph Spellman served as home until recently.  The league has amateur status with matches and training taking place outside of work hours.  Matches take place on Mondays and Tuesdays.  Equipment and uniforms are occasionally donated by organizations and benefactors with deficits being covered by the Vatican government.  The league takes place between October and May each year with a two-month break in December and January. The Vatican City national football team (Italian: "Selezione di calcio della Città del Vaticano" ) is the football team that represents Vatican City under the control of the Federazione Vaticanese Giuoco Calcio, headquartered in the Vatican's Cortile di San Damaso.  The Vatican City football association was founded in 1972.  Its current president is Domenico Ruggerio.  Gianfranco Guadagnoli, an Italian, is the current head coach.  The team has been managed by Giovanni Trapattoni in the past.  His first match as manager was played on 23 October 2010 when Vatican City faced a team composed of Italian financial police.  The team played its first match in 1985, a 3–0 victory against a representative of Austrian journalists.
