World Solve

Credit products are sometimes marketed most aggressively to people least able to manage the resulting debt responsibly. Stronger protections that don't cut off access entirely remain a difficult, unresolved balance.

Wages in many countries have grown more slowly than housing, healthcare, and food costs over the past few decades, steadily eroding real purchasing power. Reversing this trend remains a central unresolved economic challenge.

A small number of large companies control a significant share of the world's seed and agricultural input supply, raising concerns about farmer dependency and pricing power. More diverse, resilient supply structures remain underdeveloped.

Workers and entire regional economies built around coal, oil, and gas face major disruption as the world shifts to cleaner energy. A fair, well-funded transition plan for these communities remains incomplete in most countries.

Regulators sometimes come from, or later move into, the very industries they oversee, raising ongoing concerns about impartiality. Structural solutions to this revolving door problem remain inconsistently applied.

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.

Facial recognition is being deployed in policing, retail, and public spaces with vastly different rules depending on location, raising serious privacy and bias concerns. Consistent, fair regulation remains largely unbuilt.

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.

Antibiotics are widely used in livestock farming to prevent disease and promote growth, contributing significantly to antibiotic resistance in humans. Reducing this use without harming farmers' livelihoods remains a persistent unresolved challenge.

A meaningful share of people who contracted COVID-19 continue experiencing fatigue, brain fog, or other symptoms long after recovery, with no reliably effective treatment yet available. This remains a significant and only partially understood health burden.

Air pollution contributes to respiratory and cardiovascular disease in millions of people living in polluted urban areas, and treatment only addresses symptoms, not exposure. Reducing the exposure itself remains the harder, unresolved half of the problem.

Clothing production involves water use, chemical dyes, and labor spread across many countries, making its full environmental cost difficult to measure accurately. Without clear measurement, meaningful accountability remains difficult to enforce.

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.

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.

Rising seas and stronger storms are eroding coastlines faster than in the past, threatening homes and infrastructure built near the water. Affordable, effective protection methods remain limited outside of wealthy coastal areas.

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.

Assistive technology has improved, but truly seamless, affordable control of phones, computers, and home devices for people with paralysis remains out of reach for many. Progress here could dramatically improve daily independence.

Manipulated or duplicated images occasionally slip through peer review, sometimes undermining trust in published research long after the fact. Better automated verification tools remain underdeveloped for scientific publishing.

Detecting a planet in a habitable zone is only a first step, and current tools can't yet confirm whether conditions there truly support advanced life. Refining this picture would sharpen the search for life beyond Earth.
