Pat Pedraja: Our younger contestant, 13, was diagnosed with leukemia at the age of 10. Being in a minority, there were no donors in the National Marrow Donor Program Registry that matched him. He watched many other people die due to the lack of donors. Pat drove cross-country (32 cities) with his mom to get attention to this problem. He raised $140,000 and added 7,000 donors. Pretty impressive at 13.

Zander Srodes: Being a Florida boy, Zander watched endangered sea turtles mate every year, but the numbers were going down. He wanted to set an example for the younger generation, so he made over 100,000 activity books for kids in elementary school. It’s in four languages and completely free.

Adam Sterling: It is well known that there is a genocide in Sudan right now. Adam has an ancestry of genocide victims and couldn’t stand the idea of a genocide. He encourages companies to stop investing in Sudan, and nine of them have. He hopes the economic pressure will stop the genocide. The president signed a bill that he drafted and lobbied. Adam is now mentioned in the documentary “Darfur Now.”

Daniel Zoughbie: Daniel lost his grandmother due to diabetes. The hospital she was at in Palestine didn’t have the technology to help her. Remembering her, he started the Global Micro-Clinic to help the poor people in the Middle East. There are now 70 micro-clinics. He has invested $700,000 dollars in this project.

Be sure to visit DoSomething, a site that celebrates teens making a difference. Be sure to watch for the Teen Choice winner on August 4th. You can vote everyday. I personally like Adam Sterling, but my money’s on Pat Pedraja to win. Regardless of who wins, the $100,000 will go a long way.
