World Solve

historical sites being destroyed remains one of the most urgent challenges of our time. Systems currently in place are inadequate for the scale and complexity of the problem. A successful approach must work where resources are scarcest and demonstrate clear, measurable results. It should identify possible harms, respect local agency, and show how the solution can be maintained and expanded by the communities it is meant to serve.

Future progress on human development and planetary health depends on solving fragile power lines destroyed by storms. Conventional approaches have proven insufficient. The required intervention must integrate community knowledge, data and appropriate technology while remaining affordable, privacy-preserving and operable with minimal external support. Strong solutions will articulate measurable impact metrics, risk mitigation strategies, and a plan for sustained operation by local actors after the pilot phase.

Decades of aquaculture expansion destroyed vast mangrove ecosystems. Current restoration efforts suffer from low sapling survival rates and conflicts with commercial shrimp farming interests.

Newly planted young mangrove saplings are routinely washed away by increasingly intense storms before establishing deep root structures.

Wetlands filter water and protect against flooding, but restoring one once it's been drained or built over is far harder than protecting it in the first place. Better restoration techniques remain limited and expensive.

Wars, disasters, and deliberate erasure have destroyed countless historical records, leaving gaps and disputes that may never be resolved. Better methods for reconstructing or verifying history could settle long-standing disputes.

Paved surfaces send rainwater rushing into drains that quickly overflow during storms, instead of letting it soak into the ground. Cities designed to absorb water naturally would suffer far less flood damage.

According to our best theories, matter and antimatter should have destroyed each other completely after the Big Bang. Yet matter clearly won out, and we still don't know why.
