World Solve

Algal blooms can produce toxins that harm both wildlife and humans, and they're becoming more frequent as waters warm and nutrient pollution continues from agricultural runoff. Preventing these blooms before they form remains an unresolved challenge.

Overgrazing, deforestation, and changing rainfall patterns continue to push arid regions toward full desertification faster than restoration projects can reverse. Scaling effective land restoration to match the pace of degradation remains unresolved.

Colony collapse disorder continues to threaten commercial and wild bee populations that are essential for pollinating much of the global food supply. A comprehensive solution addressing all contributing factors at once remains unresolved.

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.

Seagrass meadows are highly effective at storing carbon and supporting marine life, but they continue to decline due to pollution, dredging, and coastal development. Restoring them at a pace that matches their loss remains an unresolved challenge.

Certification programs for sustainable palm oil exist, but enforcement gaps still allow rainforest clearing to continue for new plantations in various producing regions. Making sustainability certification genuinely effective at preventing this remains unresolved.

Coastal dunes provide a natural barrier against storm surges, but development and recreational use continue to erode them faster than they can naturally rebuild. Protecting these ecosystems remains an underappreciated but unresolved coastal resilience challenge.

Develop local skills, spare-parts access, inspection methods, and financing so public infrastructure continues functioning after installation. The challenge is especially acute in informal settlements, where existing solutions often assume stable institutions, high incomes, continuous connectivity, or centralized service delivery.
