We haven't built climate-resilient drinking water pipelines through landslide-prone mountain passes.
Seasonal mountain landslides routinely break main water pipelines, cutting off municipal drinking water to mountain towns for weeks.
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.

Plastics dumped in upstream countries flow down international rivers, polluting downstream nations that lack diplomatic enforcement mechanisms.
International carbon credit projects often benefit corporate developers and national governments while indigenous communities protecting the forests receive minimal revenue.
Despite recognition of its importance, reliable methods for mechanisms for ensuring that climate and development finance reaches women and marginalized groups are still lacking. Progress is hindered by incomplete mechanistic knowledge, high capital and operational barriers, and the absence of deployment models suited to the contexts of greatest need.
As some regions become less livable due to heat, drought, or flooding, governments often lack a clear, proactive plan for how internal migration should be managed. This leaves affected communities dealing with sudden, poorly supported relocation.
Treaties on climate, trade, and human rights rely on voluntary compliance, and countries that break them rarely face meaningful consequences. This makes international law more of a suggestion than a binding rule.
This means a single permanent member can stop global action on war, genocide, or humanitarian crises regardless of what the rest of the world wants. Reforming this without those same countries blocking the reform remains unresolved.
Developing countries often pay significantly higher interest rates for clean energy projects than wealthier nations, slowing their transition away from fossil fuels. Fairer, more accessible financing remains a major unresolved barrier.
Rules protecting children online vary significantly by country and platform, leaving major gaps that put young users at risk. A more consistent global standard remains politically and technically difficult to establish.
Rates of some cancers are rising among people under fifty for reasons researchers don't yet fully understand, spanning diet, environment, and other unknown factors. Identifying the cause is a necessary first step toward prevention.
Fertilizer runoff from farms feeds harmful algae blooms in nearby lakes, damaging drinking water and local ecosystems. Preventing this at the source remains cheaper than treating it after the fact, but adoption is still limited.
Mining for the metals used in batteries and electronics often destroys forests, rivers, and habitats that took centuries to form. Balancing resource needs with ecosystem protection remains a persistent unresolved tension.
Microplastics have been found nearly everywhere scientists have looked, including soil and tap water, yet no affordable removal method exists at scale. This leaves an existing, growing contamination problem largely unaddressed.
Most food waste in large cities still ends up in landfills producing methane, despite composting being a relatively simple, well-understood solution. Scaling this to city-wide adoption remains logistically unresolved in most places.
International agreements to reduce deforestation often rely on inconsistent or delayed data, making enforcement difficult. Better real-time tracking could hold countries and companies accountable for logging commitments.
Overgrazing and development have degraded vast grassland ecosystems worldwide, and restoration efforts remain small compared to the scale of the damage. A more scalable restoration method could recover important habitat and carbon storage.
Data centers powering cloud services consume enormous amounts of electricity and water for cooling, and demand keeps climbing with AI adoption. A genuinely sustainable path for this growth remains unresolved.
A large enough solar storm could damage transformers and electronics across entire continents, and current models can't precisely predict which systems would fail. Better modeling could guide smarter infrastructure protection investment.
Ocean currents regulate weather and temperature worldwide, and small changes could have outsized global effects. Current climate models still can't predict these shifts with the precision policymakers need.
Decisions today about climate, resource use, or nuclear waste will affect people who haven't been born yet and have no way to advocate for themselves. How much their future interests should count remains genuinely unresolved.
