Repository of problems worth solving
World Solve is a public institutional repository for identifying real unresolved problems across science, society, health, governance, economics, and local systems. Each entry is intended to be citable, inspectable, and actionable.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Life circumstances can change dramatically after a promise is made, and it's unclear how much this changed context should affect the moral weight of the original commitment. This unresolved tension appears in debates over long-term personal and professional commitments.

Decisions about climate change, resource use, and debt all require some answer to how much weight future, non-existent people deserve compared to those who exist now. Philosophers disagree sharply on this tradeoff.

If moral truths exist independently of human opinion, our task is to discover them; if not, morality may be more like a shared convention. This unresolved question underlies most ethical disagreements about right and wrong.

If aesthetic judgments are purely subjective, calling any art objectively better than another becomes philosophically difficult to defend. Yet most people act as though some works are genuinely superior, not just differently liked.

From childhood to old age, nearly everything about a person changes, yet we treat them as a single continuous identity, and no philosophical account of why has settled the matter. This affects questions about responsibility for past actions.

We tend to believe humanity has become more moral over time, abolishing slavery and expanding rights, but philosophers debate whether this represents real progress or just changing preferences. Settling this affects how confident we can be about future ethical judgments.

Certain industries and roles inevitably benefit from human suffering, such as disaster recovery services, raising unresolved questions about whether it's ever fully ethical to build wealth this way. This tension arises in many overlooked corners of the modern economy.

Vast amounts of carbon and methane are locked in frozen Arctic soil, and as it thaws, it could release gases faster than current climate models predict. Better prediction tools are needed to understand how much this will accelerate warming.

Excess nitrogen from agricultural fertilizer washes into rivers and eventually the ocean, fueling algae blooms that deplete oxygen and create dead zones where marine life can't survive. Reducing this runoff while maintaining crop yields remains an unresolved balancing act.
