I've raised £4000 to Send my son to Tanzania for a month to help communities build a new life for themselves. To help build homes ,schools as well as water wells

The other day while I was in school I was presented with a opportunity to help other people in a country that is not as fortunate as us; Tanzania. They said that while we are there we will be helping the local community with their lives, to improve them. It makes me feel terrible when I think that the cure for a disease ,that has no cure, might be in the mind of someone that hasn't got a proper education. It also makes me upset when I think about the fact when we are thirsty, we can just turn on the tap to get fresh water but they have to walk miles just to get a bucket of dirty water. Because of this I have decided that I want to go to Tanzania to help all of those people by building them houses and water pumps, teaching them to read and write, and help them cook. But I do get something out of it as well because I have always wanted to learn a language that isnt being provided in our curriculum and while I am there they will be teaching me Swahili.
