The students stopped as a strip of faded blue in the sand caught their eye. They tugged, slow at first, then with greater force—until a long, flat plastic pipe broke free, shedding sand as though waking from years beneath the surface.

This moment was just one of many snapshots from the Cleanup Action at Starfish Bay on 17 January 2026, when the College Environment Committee and “Here In Nature” collaborated to promote students’ environmental awareness while protecting a treasured corner of Hong Kong.

Before heading to the beach, students attended a seminar on marine environmental challenges, learning that the litter they would soon collect was only the visible tip of a far larger, hidden tide of pollution.

Visuals in the presentation revealed the silent suffering caused by plastic debris inflicts on marine life.

At first glance, the beach appeared calm and pristine. But once participants stepped beneath the shade of the mangroves, a different picture emerged: bottle caps hidden beneath driftwood, fishing lines tangled among the roots, and strips of plastic half‑buried along the tide line. What looked clean from afar quickly proved otherwise.

Piece by piece, bag by bag, the pile of waste grew. By the end, the 20 participants had gathered 41 kilograms of debris—far more than they expected. Yet even after hours of effort, trash still clung to the shoreline’s hidden corners.

Working together, the group made its way along the shoreline to remove coastal debris.

But the day concluded not with discouragement, but with clarity. Cleanups alone can never keep pace with the constant stream of debris arriving on our shores. Real change must begin long before waste reaches the sand. Choosing reusables and avoiding excess packaging, source reduction is not only the most effective solution, but the only sustainable path forward.
