Repository of problems worth solving
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.
Publicly citable
Every problem has a stable citation code for reference and discussion.
Filtered by relevance
Search by category, geography, status, and keywords.
Builder-oriented
Use the repository to find startup ideas, policy leads, and research agendas.

Some emotions are broadly considered undesirable, but it's unclear whether they're inherently unethical to feel or simply uncomfortable, natural human responses that deserve less judgment. This unresolved question touches on the ethics of emotion itself.

People often behave more ethically in some contexts than others, and it's unclear whether this inconsistency reflects a genuine character flaw or simply the natural complexity of human behavior. This unresolved tension complicates how we judge moral character overall.

Seeking validation from others is a natural human tendency, but it's unclear how much this desire compromises the authenticity of the values and choices it influences. This unresolved tension touches on both personal psychology and the philosophy of authentic living.

Some of the world's largest aquifers are being pumped for irrigation and drinking water far faster than natural processes can refill them. Once fully depleted, these ancient water reserves may take centuries to recover, if they recover at all.

Excess natural gas at oil extraction sites is often simply burned off rather than captured and used, wasting a valuable resource while releasing preventable emissions. Capturing this gas instead of flaring it remains inconsistently adopted across the industry.

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.

Degraded peatlands release significant amounts of stored carbon, and restoring them to their natural, carbon-storing state requires careful, sustained management that many restoration projects don't achieve. Making this restoration reliably effective remains unresolved.

Because clean air and water aren't priced like other resources, they're often used or polluted without any real cost attached until the damage is severe. A better way to account for their true value could change how we protect them.

The absence of robust, context-adapted solutions for methods for restoring the productivity and resilience of agricultural systems under climate change creates cascading risks across interconnected human and natural systems. Key missing elements include durable performance, low lifetime cost, and governance arrangements capable of sustaining impact beyond pilot stages.
