Who are our heroes?

As the Beijing Olympic rolls on and we celebrate the human will and spirit of competition, much is being made of athletes as spokespersons.

For example:
- U.S. basketball star LeBron James is linked with Spongebob Squarepants to teach kids what they can do to protect the earth.
- Olympic swimmer and fashion model Amanda Beard is a spokesperson for WildAid, communicating the plight of sharks
- Cyclist Adam Craig and many other Olympians have signed on with Green Laces, pledging to use recyclable shopping bags and other things to protect the environment

It has me thinking...Who are the heroes for the convergence issue? And, what should they be saying?

Thoughts?
