Cleaning water in an African village, inspiring people power in the streets, combating disease-carrying mosquitoes, learning to recycle, developing new crops and overcoming pollution. That’s just a few of the ways I saved the world yesterday.

Forgive the appalling pun in the headline. By the time you read this, I’ll be on a plane to Poland.
