What is SI? | SI Full Form | SI Term

Laudato si’ (Praise Be to You) is the second encyclical of Pope Francis, subtitled “on care for our common home”. In it, the Pope criticizes consumerism and irresponsible economic development, laments environmental degradation and global warming, and calls all people of the world to take “swift and unified global action”. The encyclical, dated 24 May 2015, was officially published at noon on 18 June 2015, accompanied by a news conference. The Vatican released the document in Italian, German, English, Spanish, French, Polish, Portuguese and Arabic, alongside the original Latin.
The encyclical is the second published by Pope Francis, after Lumen fidei (The Light of Faith), which was released in 2013. Since Lumen fidei was largely the work of Francis’s predecessor Benedict XVI, Laudato si’ is generally viewed as the first encyclical that is entirely the work of Francis.
