Ryan Hrejac is a kid who is 15 and lives in Canada. Without his help, hundreds of wells that now provide fresh water for people in Africa, Central America, and India might never have been built. He travels the world to tell people how they can help solve a big problem: the need of safe drinking water in many developing countries.

“Everybody can do something,” Ryan says.

Ryan's efforts didn't begin in a far-off place, though, but right at home in Kemptvlle, Ontario. In 1998, when he was 6 years old, Ryan learned from his teacher that children in Africa often must walk miles each day to find water. His teacher said that some of the children even died from drinking bad water.

So Ryan decided to take action. He did housework for his parents and for neighbors to make some money. He spoke to schools, churches, clubs about his idea. The word spread, and donations（捐献）began coming in. After several months of hard work, Ryan had raised $2, 000, enough to dig one well.

An organization called Canadian Physicians for Aid and Relief（CPAR）chose a place for the well in the village of Agweo, in Uganda, eastern Africa.

After the first well was built, “the ripple effect took over,” Ryan said, “and one goal led to another.”

He founded Ryan's Well Foundation（基金会）four years ago to educate people about the importance of water and help more people get clean water with others' help. Now the foundation has raised more than $1.5 million and built 255 wells that could serve more than 427,000 people in 12 countries.

Its website lists some of the famous people Ryan has met and the honors he has received.

Ryan isn't bragging（吹噓）. “The best people I've met are the other kids who want to help, too.” he said. “The only reason I accept honors is that each word I say when I get one might help one more person.”
