July 8, 2009 Update
This Tuesday, the Vatican released the Holy Father's third encyclical letter, "Caritas in Veritate" (Charity in Truth), emphasizing that "charity demands justice: recognition and respect for the legitimate rights of individuals and peoples." Focused primarily on international economic issues, Pope Benedict calls for a "true world political authority" to promote the common good of all and for "greater social responsibility" by businesses.
In this context, Benedict XVI devotes the fourth chapter of the encyclical to "The development of people, rights and duties, the environment." Here, the pope says that, "The environment is God's gift to everyone, and in our use of it we have a responsibility towards the poor, towards future generations and towards humanity as a whole."
