Pope Francis’ Encyclical Letter Laudato Si’: On Care for Our Common Home was published in June 2015 to widespread praise from such people as the Ban Ki Moon, Secretary General of the United Nations and Mary Robinson, former President of Ireland. While previous popes have spoken about the environment, this is the first time that an entire encyclical has been devoted to the environment and human ecology. In Life’s Delicate Balance, Sr Nellie McLaughlin provides an impassioned companion piece to this landmark publication. Following sincere reflection upon the text of Laudato Si’, Nellie exhorts people everywhere to pay heed to the pope’s call to save our planet from destruction. With core questions included for reflection and action, this clear and concise book is an urgent and timely wake-up call in its own right.
