Have you ever wished you could stop the spread of diseases? Or help fight hunger?

It can be as easy as taking a picture of your school lunch and posting it online. That’s what a nine-year-old in Scotland did to raise awareness about healthy eating and hunger. One young boy talked to his senator about health care. Another girl used animation skills to start a conversation about autism. These kids are all activists for health.

They noticed a problem, and they did what they could to raise awareness and fix that problem. Read their stories about how they worked to improve health, and learn how you too can be an activist.
