climate change and human trafficking

THANKS TO OUR SPONSOR:

. The Pontiff had recently drawn international press with his

encyclical on climate change

.

Hales called the Pope's remarks compelling and said he made a good case that not only were climate change huge problems worthy of global attention but that they were interrelated problems with environmental and social consequences.

We talk to Hales about how his perspective was affected by the trip to Rome, and what changes he might want to make as a result.
