This topic is very difficult for me. The true is I`ve never thought about this, one person public or famous is not always worthy of admiration, but if a have to choose someone would be Ryan Hreljac.

 I knew him when I read a story on Internet. He was born in 1991 in Canada, when he was a child of six years his teacher told him about African and their life conditions like children of his age who die of thirst. This caught his attention and he decided to raised money to buy a water hole to Africans. After having saved enough money with his family and community, in 1999 it was built the first water hole. When he was nineteen years old he has already built 432 water hole in the  Africa continent. Today he have a foundation called “Ryan`s well” and have projects of education and built of water hole in more than sixteen countries of African Continent. 

For me he is a person very important in the world, because it has helped many African to improve their life conditions with something so basic as water. 

If a meet him some day  first I would ask him what was your main motivation to create the foundation, why he think the Africans have poor life conditions and who he can expands his foundation to more countries. 

If all people help a bit could make big changes.
