The last time I looked, there were about seven billion people on this planet. There are all sorts of candidates for the Nobel Peace Prize. Across the developing world, you will find gaunt and patient aid workers who have consecrated their lives to ending tribal conflicts. There are bone-nosed eco-warriors who are fighting to save the peoples of the rainforest from destruction. There are women who are struggling for female emancipation in Saudi Arabia. In tyrannies from Uzbekistan to North Korea, there are journalists risking their lives so the truth can be heard. There are good people battling every scourge, from famine to gun-running to piracy to human trafficking.
