We don't have a shared global archive that preserves human knowledge against catastrophic loss.
open
Global / Unspecified, Global
Most human knowledge lives in systems vulnerable to disaster, conflict, or simple neglect, with no single resilient backup for civilization's collective information. A well-protected global archive could safeguard this against permanent loss.

We haven't solved how to make scientific research results replicate consistently across different labs.
open
Global / Unspecified, Global
A surprising number of published scientific results can't be reproduced when other researchers try the same experiment, undermining trust in published findings. Fixing this reproducibility gap is essential to keeping science reliable.

We don't have a reliable global system for tracking and stopping wildlife trafficking.
open
Global / Unspecified, Global
Illegal wildlife trade pushes species toward extinction while operating largely undetected across international borders. A more coordinated global tracking system could catch this trade before, not after, populations collapse.

We haven't found a fair way to govern the deep sea, which belongs to no single nation.
open
Global / Unspecified, Global
The deep ocean holds vast mineral resources and ecosystems we barely understand, yet no single country has authority over most of it. Without a fair governance system, the deep sea risks being exploited before it's even properly studied.
Citation ID: WS00147
Title: We haven't found a fair way to govern the deep sea, which belongs to no single nation.

We don't have an affordable way to preserve cultural heritage sites threatened by war or climate change.
open
Global / Unspecified, Global
Historic sites are being lost to conflict, flooding, and neglect faster than preservation efforts can keep up, often permanently. Cheaper, faster preservation methods could save irreplaceable pieces of human history.

We haven't solved how to make space exploration a shared, not just national, achievement.
open
Global / Unspecified, Global
Space missions are still largely framed as national or corporate accomplishments rather than shared human ones, even though the benefits and risks affect everyone. A more collaborative model could accelerate progress and broaden its benefits.

We haven't found a way to make disaster relief reach victims within the first critical hours consistently.
open
Global / Unspecified, Global
The first hours after a disaster are often the most critical for saving lives, yet aid frequently takes days to arrive due to logistics and coordination failures. Closing this gap could save many lives that are currently lost to delay alone.
