How Can InfoSec Change the World?

Something that has been really bothering me lately has been the subject of changing the world. I'd like to, but I'm having a tough time figuring out how. So, I have a simple question for anyone who can chime in: How can you use Information Security to change the world?

Here's some further explanation:

• I realize that making the world's networks more secure can make the world a better place. Computers run our world, and we need them in order to do even the most basic things in life.
  
• Day-to-day work of enhancing network security isn't enough for me. I want to have a bigger impact.
• I don't want to sit in a room with a "working group" and talk about ways to make the world better, I want to actually do hands-on work to make a difference.
