World Solve

This parasitic disease continues to cause preventable blindness in parts of Africa and Latin America, largely due to limited access to consistent treatment. Expanding affordable access remains the main barrier rather than lack of an effective treatment.

Highly effective hepatitis C treatments exist, but cost and healthcare access still prevent many infected people worldwide from receiving them. Expanding affordable access remains the primary barrier rather than the science itself.

Effective vaccines exist for a small number of sexually transmitted infections, but many common ones still have no vaccine available at all. Expanding vaccine coverage here could significantly reduce global disease burden.

Surveillance capabilities have expanded rapidly, but the oversight meant to prevent abuse often lags behind, staffed by bodies with limited authority or access. This leaves citizens with little real assurance surveillance powers aren't being misused.

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.

Surveillance capabilities often grow quietly, justified by security concerns, with limited public awareness or debate about their true scope. Building lasting oversight mechanisms remains a persistent democratic challenge.

Artificial lighting confuses migration patterns, hunting behavior, and reproduction cycles in many nocturnal species, yet city lighting keeps expanding with growth. A widely adopted, wildlife-friendly lighting standard remains missing.

This period, known as cosmic inflation, is widely accepted as a concept but the exact physical mechanism driving it remains unproven. Confirming it would close a major gap in our understanding of the universe's first moments.

Larger asteroids are easier to spot years ahead, but smaller ones capable of serious regional damage often go undetected until they're very close. Expanding detection capability remains a quiet but serious safety gap.

We tend to believe humanity has become more moral over time, abolishing slavery and expanding rights, but philosophers debate whether this represents real progress or just changing preferences. Settling this affects how confident we can be about future ethical judgments.

As farmland expands to meet growing food demand, it frequently cuts through pathways that wildlife species depend on for seasonal migration. Balancing agricultural needs with preserving these corridors remains an unresolved land-use challenge.

As temperatures rise, mosquitoes and other disease-carrying insects are expanding into regions that were previously too cold for them to survive, introducing new health and ecological risks. Tracking and responding to this shift remains an unresolved public health and conservation challenge.

As cities and suburbs expand, they often replace the wildflower meadows and natural habitats that pollinators depend on with lawns and pavement. Designing urban growth that preserves pollinator habitat remains inconsistently practiced.

As demand grows for minerals used in batteries and electronics, deep-sea mining is expanding into ecosystems that remain poorly understood and could take centuries to recover from disruption. Regulating this before major damage occurs remains an unresolved governance and environmental challenge.

Fabricated professional licenses generated to appear authentic could potentially deceive employers or clients who don't have direct access to official verification databases. Expanding accessible, reliable verification systems remains an unresolved challenge globally.

Aircraft safety relies heavily on scheduled inspections rather than continuous, real-time structural monitoring, since affordable sensors capable of this level of detail remain limited. Expanding this kind of predictive monitoring remains an unresolved aviation challenge.

Telemedicine can expand healthcare access, but its usefulness is limited in areas where internet connectivity is too unreliable to support video consultations consistently. Solving this connectivity dependency remains an unresolved infrastructure challenge.

Wealthier countries can screen for many rare genetic conditions at birth, but most of the world's newborns are never tested. Expanding this access could catch treatable conditions before irreversible damage occurs.

Women-led microenterprises in Philippines face disproportionate barriers to opening and maintaining formal savings accounts, limiting their capacity to reinvest and grow their businesses.

Create predictive maintenance and equipment-upgrade strategies for overloaded local grids serving growing cities and newly electrified rural areas.
