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 don't have a global system to fairly share the cost of climate damage between rich and poor nations.

open Global / Unspecified, Global

Wealthy nations have historically emitted the most greenhouse gases, but poorer nations often suffer the worst climate damage. Without a fair cost-sharing system, climate justice remains mostly a talking point rather than a policy.

We haven't solved how to recycle batteries and electronics without toxic waste byproducts.

open Global / Unspecified, Global

Current recycling methods for batteries often use harsh chemicals or produce hazardous waste of their own. A cleaner recycling process would make the growing battery industry far more sustainable.

We can't yet track and stop illegal deforestation as it happens in real time.

open Global / Unspecified, Global

By the time illegal logging is discovered, the trees are often already gone and the damage is done. Real-time detection and enforcement could protect forests before, not after, they disappear.

We don't have a reliable way to desalinate seawater cheaply enough for widespread drinking use.

open Global / Unspecified, Global

Turning seawater into drinking water is technically possible but still too energy-intensive and expensive for many water-scarce regions. Cheaper desalination could solve water shortages for millions of people.

We haven't found a way to farm food without depleting the soil that grows it.

open Global / Unspecified, Global

Modern farming often strips soil of nutrients faster than nature can replace them, threatening long-term food production. A farming method that restores rather than depletes soil could secure food supply for generations.

We can't stop plastic waste from accumulating in oceans faster than we clean it up.

open Global / Unspecified, Global

Millions of tons of plastic enter the ocean every year, and cleanup efforts remove only a small fraction of it. Without cutting the source and scaling removal, marine ecosystems will keep absorbing the damage.

We don't have affordable technology to remove carbon dioxide from the atmosphere at meaningful scale.

open Global / Unspecified, Global

Direct air capture exists, but it's still far too expensive and energy-intensive to make a dent in global emissions. Making it cheap enough to scale is one of the biggest levers left for slowing climate change.

We don't have a widely trusted way to prove a person online is actually a real human.

open Global / Unspecified, Global

As AI-generated accounts and bots flood social platforms, telling a real person from an automated one is getting harder. Without a trusted verification method, online trust and public discourse both suffer.

We haven't built translation technology that fully preserves tone, culture, and nuance across languages.

Machine translation is fast and often accurate, but it still misses jokes, idioms, and cultural context that change meaning entirely. Real cross-cultural communication needs more than word-for-word accuracy.

We can't guarantee that personal data, once deleted, is truly gone from every system that touched it.

open Global / Unspecified, Global

Data gets copied, backed up, and shared across so many servers that a single delete request rarely removes every trace. Real digital privacy requires a technical guarantee that deletion actually means deletion.

We haven't solved how to make software supply chains fully verifiable from source to user.

open United States, North America

Modern software is built from thousands of smaller components, any of which could be secretly tampered with. Without full traceability, a single compromised piece can quietly infect software used by millions.

We can't build robots that move and adapt in unpredictable environments as well as animals do.

Even the best robots struggle with uneven terrain, sudden obstacles, or tasks requiring fine motor control that animals handle instinctively. Closing this gap would open up robotics for disaster response, farming, and elder care.

We don't have a legal framework that assigns responsibility when AI systems cause harm.

open Global / Unspecified, Global

When an AI makes a harmful decision, it's often unclear whether the blame falls on the developer, the user, or the company deploying it. Without clear rules, victims of AI mistakes often have no clear path to accountability.
