When Students Stand Up to Speak, a Nation Starts to Listen

In a packed auditorium, a fifteen-year-old from a rural school in Sri Lanka gripped the edges of a podium and began arguing why her generation could no longer afford to ignore plastic pollution. Across from her, a team from another district prepared their rebuttal, armed with statistics about single-use plastics choking the island’s waterways. This was not a typical school debate. This was හරිතාභිෂේක’26, and the stakes felt personal for every student in the room.

A Platform Built by University Students for School Students

හරිතාභිෂේක’26 is an All Island Inter-School Debating Competition organized by ZeroPlastic Colombo Community, the University of Colombo chapter of the ZeroPlastic Movement. The project was designed with a specific and urgent purpose: to promote awareness on the reduction of plastic usage and to encourage sustainable alternatives to plastic and polythene among Sri Lanka’s youngest generation of thinkers.

By choosing the format of a debating competition, the organizers made a deliberate decision. Rather than delivering lectures or distributing pamphlets, they handed the microphone to school students and asked them to research, reason and argue their way through the complexities of environmental conservation. The result was something far more powerful than a one-way awareness campaign. Students had to wrestle with real questions about consumer habits, economic trade-offs and the feasibility of a circular economy in a developing nation.

There is something uniquely effective about requiring young people to argue both sides of an environmental issue. A student who must defend the case for sustainable alternatives one round and challenge its practicality the next walks away with a deeper, more honest understanding of the problem. That kind of critical engagement is exactly what the fight against plastic pollution demands…
