World Solve

The problem of medicinal plants disappearing continues to affect hundreds of millions of people and undermines progress on multiple Sustainable Development Goals. Existing responses remain fragmented, under-resourced and poorly adapted to local contexts. A strong solution must operate effectively under severe constraints of skilled personnel, infrastructure, electricity and connectivity. It should define clear measurable outcomes, identify possible unintended harms, and demonstrate how the intervention can be sustained by local institutions long after initial funding ends.

Addressing knowledge of plants being lost is critical for achieving the 2030 Agenda. Current efforts fall short in scale, speed and equity, leaving the most vulnerable behind. Any viable solution must function in low-resource settings with limited specialists, transport, laboratory capacity and broadband. Proposals should specify quantifiable biological, social or environmental outcomes, openly discuss potential risks, and present a realistic pathway for long-term maintenance and local ownership beyond short research pilots.

rapid spread of plant diseases 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.

Access rules that demand deposition of a memory before entry turn recreation into an emotional transaction. The challenge is preserving green-space availability without compulsory self-disclosure.

If facial appearance can be altered continuously through filters or implants, both social recognition and security systems lose stable anchors. The problem is maintaining trustworthy identity verification and human connection without requiring permanent biometric locks that themselves create new risks.

When companion animals gain the ability to express complex preferences and demands, existing ownership models break down. The problem is defining rights, responsibilities, and welfare standards that protect both animals and humans without creating unmanageable legal or social burdens.

Rapid language change driven by neural interfaces may make ordinary conversation between grandparents and grandchildren impossible without permanent translation layers. The problem is preserving mutual understanding and cultural continuity without forcing everyone onto the same implant standard or erasing linguistic diversity.

Implanted medical devices like pacemakers increasingly connect wirelessly for monitoring, but security protections for these devices haven't kept pace with the sensitivity of what's at stake if they're compromised. Closing this gap remains an urgent but underaddressed challenge.

Over the next 10–20 years, biosensors will track vital signs, metabolites, and behaviours, but analytics and integration into care will lag. Edge-computing and clinically validated algorithms will be needed.

Untreated sewage pollutes rivers and coasts. Decentralized treatment plants and enforcement are needed.

Many plants remain stuck in low-tech production. Technology-transfer and cluster strategies can accelerate upgrading.

Farmers burn leftover stubble to quickly clear fields for the next planting season, despite bans and health costs. Affordable stubble-collection machinery and biomass-to-energy ventures could offer alternatives.

Aging farming populations struggle to find workers during planting and harvest seasons, especially in East Asia. Affordable small-scale farm automation and shared-equipment rental platforms could offset labor gaps.

Most crop research targets temperate climates, leaving African staples like sorghum and cassava under-optimized for drought and heat. More localized plant-breeding research is needed urgently.

Plants grown in space suffer from water-logging and oxygen starvation around roots due to absence of buoyancy-driven convection. Developing autonomous micro-fluidic aeration root systems is essential for growing fresh crops in space.

While microgravity (0g) is well-studied, long-term multi-generational plant reproduction under lunar (0.16g) or Martian (0.38g) gravity is unverified. Long-term surface greenhouse experiments are urgently needed.

Asia operates hundreds of young, high-emitting coal plants protected by long-term power purchase agreements. Early retirement initiatives face severe financial losses and political resistance from domestic energy sectors.

Critical peatlands and ancient rainforests in Sumatra and Kalimantan are continuously drained and burned for monoculture crops, releasing vast carbon reservoirs and driving endangered species like orangutans toward extinction.

Inland freshwater fishermen lose significant portions of their daily catch due to lack of localized ice plants and affordable off-grid refrigeration.
