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.

Some frameworks emphasize the intentions behind an act, while others focus purely on the actual consequences, leading to very different moral judgments in identical situations. This unresolved tension remains a foundational issue in ethical theory.

Many major rivers depend on glacial melt for a steady water supply, and as these glaciers shrink, the long-term water security of downstream populations becomes increasingly uncertain. Protecting or planning around this shrinking resource remains unresolved.
