Why This Matters

Marine debris does not only appear on beaches. It accumulates underwater, becomes trapped in coastal habitats, and continues affecting marine life over time.

Many cleanup efforts remove waste — but the information behind what is found is often lost.

OGU believes that:

  • Cleanup should be documented
  • Findings should be shared
  • Data should remain accessible

So that every effort contributes to a clearer understanding of Hong Kong’s marine environment.

Citizen Science

OGU encourages responsible environmental observation through participation.

Citizen science, in our context, means:

  • Recording what is found in the field
  • Sharing real observations
  • Contributing to a growing public record

Not only cleaning, but also documenting.

This allows environmental information to remain visible and useful for awareness, research, and future action.
