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.

As digital platforms increasingly influence what people see, believe, and desire, it's unclear how much this shapes authentic identity versus manufactured preference. This unresolved question grows more urgent as algorithmic influence deepens in everyday life.

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.

Kelp forests support diverse marine ecosystems but are increasingly vulnerable to warming waters and invasive species that outcompete them once they weaken. Restoring and protecting these ecosystems at scale remains an unresolved conservation challenge.

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.

As temperatures rise, alpine species are forced to migrate to higher elevations, but many eventually run out of mountain left to climb, risking extinction. Protecting these increasingly squeezed ecosystems remains an unresolved conservation priority.

River deltas provide fertile land for millions of people but are increasingly eroding due to upstream dam construction and rising sea levels reducing natural sediment replenishment. Protecting these critical, densely populated areas remains an unresolved challenge.

Forests act as natural carbon sinks, but increasingly severe wildfires are turning some forests from carbon absorbers into carbon emitters faster than they can regrow and recover. Reversing this shift remains an unresolved climate feedback challenge.

As AI systems increasingly influence what billions of people see, believe, and decide, someone is effectively choosing the values baked into those systems. There's no agreed process for who that someone should be, or how they should be held accountable.

As automation and AI displace routine and increasingly cognitive labor, most economies still assume most people need traditional jobs to survive and find purpose. Without a credible alternative, mass automation risks instability rather than shared benefit.
