Tony P. Hall is one of those rarest of creatures, a true humanitarian who used his positions (a Congressman from Ohio and Ambassador to the U.N) of power and influence to aid the world's poor and hungry. Changing the Face of Hunger inspires us to action to address modern day's greatest injustice, that too many of the world's peoples will die unnecessarily as a result of hunger and disease. Tony Hall's call for us to follow the example of Mother Teresa and "do what's in front of us" in combating life's injustices is today's clarion calling. Read this book and change the world.
