By Christopher Lamb, CNN(CNN) — Pope Leo XIV has called for pressure to be placed on governments to protect the environment as he stressed that damaging the natural world is incompatible with the Christian faith, in a speech at a climate conference Wednesday. “We cannot love God, whom we cannot see, while despising his creatures” Leo told the conference which was held to mark 10 years since Pope Francis’ landmark document on the environment. They were the organisers of the event at Castel Gandolfo at which Leo spoke Wednesday. Among those attending the event was Arnold Schwarzenegger, the actor and former Governor of California, who is supporting papal efforts on climate. “We must shift from collecting data to caring,” he said before making a final appeal.
