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.

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.

Factory farming, animal testing, and habitat destruction all cause animal suffering for human benefit, but there's no consistent ethical standard for how much suffering is acceptable and why. This gap shows up in inconsistent laws and practices worldwide.

Billions of dollars in foreign aid have flowed for decades, yet the gap between wealthy and poor nations remains wide. This suggests aid alone isn't the missing piece, and a better approach is still needed.

Criminal networks move money, goods, and people across borders quickly, while law enforcement cooperation between countries is often slow and limited. Closing this gap requires faster, more trusted international coordination.

Getting a broken bone fixed is usually straightforward; getting consistent mental health support often isn't, due to cost, stigma, and shortage of providers. Closing this gap could prevent enormous, often invisible suffering.

Current approaches to real-time monitoring and response systems for industrial chemical and oil spill events either underperform under variable field conditions or generate externalities that undermine long-term sustainability and equity. Closing the gap requires coordinated advances in science, systems design and enabling institutions.

A persistent gap exists in realizing practical, scalable solutions for industrial-scale lunar propellant and structural material production. Scientific understanding, engineering readiness and institutional capacity remain insufficient to translate promising concepts into durable impact under real-world constraints of cost, skills and governance.
