Political Science

Single-use plastics provide us a moment of convenience, but they have long-term negative consequences. I want to live in a world where single-use plastics DO NOT exist! I am on a mission to turn my dream into a reality.

How she's a changemaker

I am the founder of TumblerShare, a social venture that helps the SFU community reduce the number of disposable cups on campus through a sharing-economy based program. We are launching a TumblerShare app to streamline our members’ experience which will help them live a more sustainable lifestyle.

How can others get involved?
