World Solve — A living repository of problems worth solving.

What World Solve is

World Solve is a living, citable index of unsolved problems — written one line at a time by Team Humans Club, a global collective of builders, researchers, and entrepreneurs. We do not solve the problems here. We Democratize Innovation.

For builders Skip the search for a problem worth your time. Browse a vetted, growing list and start where the gap is real.

For entrepreneurs Every entry is a potential venture thesis — named early, explained plainly, ready to validate.

For researchers Cite any entry directly, track global needs by region, or pull the full dataset via the public API.

We haven't solved how to farm livestock without contributing heavily to greenhouse gas emissions.

open Global / Unspecified, Global

Raising cattle and other livestock produces a significant share of global methane emissions, yet meat remains a major part of diets worldwide. A lower-emission farming method that doesn't require giving up meat entirely remains unsolved.

We can't yet track ocean plastic pollution accurately enough to know exactly where it's coming from.

open Global / Unspecified, Global

Plastic waste in the ocean is well documented, but pinpointing exact sources at a granular level remains difficult, making targeted prevention harder. Better tracking could focus cleanup and policy efforts where they matter most.

We haven't found a scalable way to teach basic coding skills to students in under-resourced schools worldwide.

open Global / Unspecified, Global

Coding education often depends on expensive devices, reliable internet, and trained teachers, none of which are guaranteed in poorer school systems. Closing this gap could open technology careers to far more young people.

We can't build computer memory that's both extremely fast and extremely cheap at the same time.

We don't have a foolproof way to stop AI chatbots from confidently stating false information as fact.
