We don't have a scalable way to prevent illegal wildlife trafficking from pushing endangered species toward extinction.

open Global / Unspecified, Global

Poaching and illegal trade continue to threaten species like elephants, rhinos, and pangolins despite international protections, because enforcement remains inconsistent and demand persists. Closing this gap between law and enforcement remains an unresolved global conservation issue.

We don't have a scalable way to prevent overfishing of shark populations that are slow to reproduce and recover.

We don't have an effective way to prevent nitrogen runoff from fertilizer use from creating massive ocean dead zones.

open Global / Unspecified, Global

Excess nitrogen from agricultural fertilizer washes into rivers and eventually the ocean, fueling algae blooms that deplete oxygen and create dead zones where marine life can't survive. Reducing this runoff while maintaining crop yields remains an unresolved balancing act.
