"Tranquility in difficult times like ours seems irresponsible. Each of us must act quickly and together, because the clock is against us. We must mobilize to define a new direction for our lives on this planet, if we want to continue inhabiting it (...) The time has begun for awareness of the finiteness of all things, including that which seemed most perennial to us: the persistence of Earth's vitality, the continued balance of the biosphere, and the immortality of the human species." One of the world's greatest theologians and a staunch defender of environmental awareness, Leonardo Boff, is releasing a new book—complete with his vast body of work, which includes over 70 books published in several languages—on one of the issues that most concerns the planet's population: how to overcome the current ecological crisis, aggravated by global warming, to avoid a situation that threatens the future of humanity. We have reached a point where the foundations of our survival as a human species are threatened. However, this threat doesn't come from some low-flying meteor like the one that once wiped out the dinosaurs, but from something more immediate and everyday: human actions, so disrespectful of the rhythms of nature and the Earth's dynamics. Our planet, this superorganism that self-regulates to stay alive and produce what we need to survive, is being decimated. We need to restore its lost balance, and for life and civilization to be saved, it's important to care for this planet as we care for our mothers. A limited planet cannot support an unlimited project. In "CARING FOR THE EARTH, PROTECTING LIFE: HOW TO AVOID THE END OF THE WORLD," Leonardo Boff warns that the set of crises plaguing humanity points us to a single crisis: that of our way of living, coexisting, and relating to nature, exploiting it limitlessly for material gain.
