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.

Some long-term ethical frameworks argue humanity's continued existence matters more than any individual's current suffering, while others reject sacrificing real people for abstract future outcomes. This unresolved tension is increasingly relevant to debates on existential risk.
