ROME — Pope Francis commemorated Earth Day on Monday by warning that the planet is “falling into ruin” thanks to humanity’s failure to protect it. “Our generation has bequeathed many riches, but we have failed to protect the planet and we are not safeguarding peace,” the pontiff chided on X (former Twitter) “We are called to become artisans and caretakers of our common home, the Earth which is ‘falling into ruin,’” he declared, followed by “#EarthDay.”
