Francis, who hails from Buenos Aires, holds a particular affinity for the environmentalist movement due to the wide scale deforestation of rainforests in his native South America. In his speech, he referred to the destroyed forests in South America as his homeland, and as land that “can no longer give life.” He also takes his name from Saint Francis of Assisi, know as the patron saint of not only the environment, but animals as well.
During his talk at the University of Molise, Pope Francis spoke on his own terms about the necessity of confronting climate change: “This is one of the greatest challenges of our time: to convert ourselves to a type of development that knows how to respect creation.”
