MEXICO CITY, Aug 11 2015 (IPS) – A few centuries ago, the biotechnology industry would have been able to buy a papal bull to expiate its sins and grant it redemption. But in his encyclical on the environment, “Laudato Si”, Pope Francis condemns genetically modified organisms (GMOs) without leaving room for a pardon.

In his second encyclical since he became pope on Mar. 13, 2013 – but the first that is entirely his work – Jorge Mario Bergoglio criticises the social, economic and agricultural impacts of GMOs and calls for a broad scientific debate.

Laudato Si – “Praise be to you, my Lord” in medieval Italian – takes its title from Saint Francis of Assisi’s 13th-century Canticle of the Sun, one of whose verses is: “Be praised, my Lord, through our sister Mother Earth, who feeds us and rules us, and produces various fruits with colored flowers and herbs.”

It is the first encyclical in history dedicated to the environment and reflecting on “our common home” – planet earth.
