Friday marks World Humanitarian Day. UN Secretary General Ban Ki-moon has called on the world to raise more money for humanitarian missions, as millions of people are relying on them to survive.

An estimated 130 million that's the number of people the United Nations says depend on humanitarian aid today. The largest number on record.

Grouped together, they would be the tenth most populous nation in the world.

That's the message from U.N. Secretary-General Ban Ki-moon as the international agency marks World Humanitarian Day,

UN launches "World You'd Rather" digital campaign

with a theme of "One Humanity" and a digital campaign called the "World You'd Rather.."

It involves taking an on-line quiz to answer some difficult questions like these.

Would you rather drink cholera-contaminated water or cross a minefield to get clean water? Would you rather eat rotten food found among tsunami debris or go hungry? Would you rather struggle for months or years in a makeshift camp or pay a smuggler and risk drowning at sea?

Grim questions, but it certainly puts you in the shoes of those faced with these decisions every day.

Series of events scheduled to show humanitarian works

A series of events are scheduled at the U.N. to show the human faces behind the staggering numbers of those in need, the dreams of people affected by crises stretching from Asia to Africa, and the tireless efforts of aid workers who risk their lives to get food and medicine to those in dire need.

The occasion is tied to the World Humanitarian Summit held three months ago in Turkey where world leaders pledged to do more for people caught up in conflicts, crises and disasters.

UN chief calls for more help for those in need

And U.N. Chief Ban Ki-moon is asking global citizens to remind their leaders to keep to those promises.

The U.N. needs more resources, funding and safe access for deliveries.

While Syria has been described as the worst humanitarian tragedy of our time, a map from the U.N.'s humanitarian affairs agency shows 60 percent of humanitarian needs coming from African nations, from Libya in the north to Zimbabwe in the South, from Mali in the West, to Somalia in the East.

The U.N. Under-Secretary General for the Coordination of Humanitarian Affairs Stephen O'Brien says the U.N. has raised nearly 22 billion dollars so far this year, but that's not enough.
