“It was great getting a chance to show off our expertise for the day to so many people. As a presenter I felt like I made a real connection with the students visiting, because I understood how to make the information truly interesting to them. And it was great hearing from teachers and other adults that I was helping them learn a lot more about my topic.”

Become a Peer Leader in Sustainability

CELF provides resources and training for high school students to become peer leaders in current sustainability issues as CELF Student Ambassadors.

  • Are you interested in learning how to create real solutions to real problems?
  • Do you have questions about the impact of climate change in your lifetime?
  • Do you wonder about the continued availability of fresh water and food to feed a growing population?
  • Have you thought about what it means to move beyond carbon to meet future energy needs?

Join a community of like-minded students to learn about these issues, share your knowledge at community events and collaborate with your peers.

Connect your Passion with a Mission: LifeStraw® STEM & Service

You don’t have to become a CELF Student Ambassador to make a difference. Learn about the fresh water issues and how your school or community group can join our CELF "100 Schools" Campaign to bring fresh water to communities that lack this essential resource.
