Millions of children are taught in non-native national languages, hindering early literacy. Digital tools lack high-quality speech recognition for under-resourced regional dialects.

High electricity costs lead small-scale leather and textile processors to bypass treatment systems, dumping heavy metals directly into river basins.

Standard lithium-ion battery arrays suffer accelerated degradation in tropical ambient temperatures, making grid-scale battery storage prohibitively expensive.

Developing Asian countries spend more on servicing foreign debt than on climate adaptation. International financial institutions have not scaled debt swaps effectively.

Commercial seaweed farming faces high initial equipment costs and fragile processing supply chains, delaying its potential for carbon sequestration.

Complex, legacy land ownership patterns in urban centers make land assembly prohibitively expensive for municipal social housing development.

Many children with obesity go on to develop related health issues as adults, and current interventions haven't proven consistently effective at reversing childhood obesity at a population scale. A more effective, scalable approach remains an urgent unmet need.

A persistent gap exists in realizing practical, scalable solutions for technologies for the safe and efficient long-term storage of renewable energy at seasonal scales. 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.

Volunteer-collected data can expand research at a scale professional scientists alone couldn't achieve, but ensuring its accuracy and consistency remains an unresolved challenge for researchers who want to use it.

Undiagnosed vision problems in children can quietly affect school performance for years before being caught. Early, affordable screening at scale remains unavailable in many school systems worldwide.

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.

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.

Digital voting could make elections more accessible, but concerns about tampering and verification have kept most systems limited to smaller-scale trials. A fully trusted, secure digital voting system remains unbuilt at national scale.

Cryptocurrency regulation varies wildly by country, creating loopholes that enable fraud and money laundering to move freely across borders. A more consistent global approach remains politically difficult to achieve.

Blood donation shortages remain a recurring problem worldwide, especially during emergencies when demand spikes suddenly. Lab-grown blood could remove dependence on donor supply entirely, but the technology isn't yet practical at scale.

Wave energy is abundant and largely untapped, but current technology to harness it reliably and affordably lags far behind wind and solar. Cracking this could add a major renewable source to the global energy mix.

Many products marketed as biodegradable still break down into tiny plastic particles that persist in the environment for years. A truly safe, fully compostable packaging material remains elusive at scale.

Farms produce enormous amounts of leftover plant material that mostly gets burned or discarded rather than turned into usable energy. Affordable, small-scale conversion technology could turn this waste into a valuable resource.

Living without normal gravity weakens astronauts' bones and muscles over time. Practical, affordable ways to simulate gravity in space stations remain mostly untested at scale.

Some games are proven to always end in a draw or a specific winner under perfect play, but for many complex games, this remains unresolved due to sheer computational scale. This unsolved area touches game theory, logic, and computer science.
