I can help people in a FLOOD-DROUGHT situation

What more can I do when so many people die through no fault of their own, I thought I would try to help the poor, poor people live a better life in some way for next to nothing as a designer and Inventor in my spare time, which I know how I can do in my own way, but I can't do it without help. I've asked so many people who could help me, but it's like shouting down a well. We've spent alot of our money on trying to save millions of lives with no success so far, so I'm used to being disappointed, the SAD part is lives have been lost when I know anyone of my very simple to make ideas could have saved them if used in some way. What more can I offer to do to help save a life done in my own way, without help from YOU.
