The Vatican has recently announced the Pope’s prayer intentions for 2013. As Catholic Culture explains here,
The practice of proposing specific monthly prayer intentions to the faithful arose in response to the formation of the Apostleship of Prayer during the nineteenth century. Members of the apostolate, founded in 1844, make a daily offering of themselves, in union with the Holy Sacrifice of the Mass, for the intentions of the Holy Father.
In the March intention for 2013, the following prayer is found: That respect for nature may grow with the awareness that all creation is God’s work entrusted to human responsibility.
For a full list of the 2013 intentions see the Vatican News service page here. The new and popular Vatican News portal also has an article on the environment here, referring to the Pope’s environmental statements at his address to Diplomats and reminds us of the UN’s “International Year of Sustainable Energy for All”.
