The news isn't all bad, says Philip Yancey. Some positive developments in the world since 1980:

*The world illiteracy rate has dropped from 53% to 20%
*The percentage of people suffering from malnutrition has dropped by more than half, to 20%.
*Only 25% used to have access to clean water; now, 75% have it.
*Global infant mortality has dropped from one in eight to one in 16.
