Kelp forests support diverse marine ecosystems but are increasingly vulnerable to warming waters and invasive species that outcompete them once they weaken. Restoring and protecting these ecosystems at scale remains an unresolved conservation challenge.

Mangroves protect coastlines from storms and support rich ecosystems, but they continue to be cleared for development faster than restoration efforts can replace them. Speeding up restoration while slowing clearance remains unresolved.

As Arctic ice recedes, increased shipping and resource extraction activity adds further pressure to already fragile polar ecosystems. Balancing economic interest with ecological protection in this newly accessible region remains unresolved.

Many major rivers depend on glacial melt for a steady water supply, and as these glaciers shrink, the long-term water security of downstream populations becomes increasingly uncertain. Protecting or planning around this shrinking resource remains unresolved.

Tropical forests host a huge share of the world's biodiversity, and converting this land for farming, even when done for legitimate food needs, often results in permanent species loss. Balancing food production with biodiversity protection remains unresolved.

A fungal disease combined with habitat destruction has driven sharp declines in amphibian populations across many regions, and effective large-scale intervention remains limited. Protecting these ecologically important species remains an unresolved conservation priority.

Old-growth forests support unique biodiversity that can't simply be replaced by planting new trees, since the ecological complexity takes centuries to develop. Protecting the last remaining old-growth forests remains an urgent, unresolved conservation priority.

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.

Biodegradable packaging alternatives exist but often don't yet match the protective qualities of traditional plastic needed to keep food safe and fresh for the same duration. Closing this performance gap remains an unresolved materials science challenge.

Sharks reproduce much more slowly than most fish, making their populations especially vulnerable to overfishing and slow to recover even after protective measures are introduced. Enforcing sustainable limits globally remains an unresolved challenge.

As temperatures rise, alpine species are forced to migrate to higher elevations, but many eventually run out of mountain left to climb, risking extinction. Protecting these increasingly squeezed ecosystems remains an unresolved conservation priority.

Many e-waste recycling operations, particularly in lower-income countries, expose workers to toxic materials with inadequate safety protections. Making this growing industry both effective and safe for workers remains an unresolved labor and environmental issue.

Invasive plants can spread aggressively in protected parks and reserves, outcompeting native species even where conservation efforts are actively underway. Effective, affordable control methods that don't damage the broader ecosystem remain incomplete.

Vultures help prevent disease spread by consuming carcasses quickly, but populations have declined sharply in various regions due to poisoning and habitat loss. Protecting this often-overlooked but ecologically important species remains an unresolved conservation issue.

River deltas provide fertile land for millions of people but are increasingly eroding due to upstream dam construction and rising sea levels reducing natural sediment replenishment. Protecting these critical, densely populated areas remains an unresolved challenge.

Monarch butterflies depend on specific milkweed habitats along their long migration routes, and the loss of this habitat across multiple countries has contributed to sharp population declines. Coordinating protection across their entire migratory range remains unresolved.

Freshwater mussels play an important role in filtering water and supporting aquatic ecosystems, but they're highly sensitive to pollution and warming, and many populations are declining as a result. Protecting this often overlooked species remains an unresolved conservation issue.

Solar and wind farms are essential for clean energy but can sometimes be built in locations that disrupt sensitive wildlife habitats if siting isn't carefully planned. Balancing rapid renewable deployment with habitat protection remains an ongoing challenge.

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.

Managed honeybees, while important for agriculture, can sometimes outcompete native pollinator species for food resources when placed in sensitive natural areas. Balancing agricultural pollination needs with native species protection remains an unresolved ecological challenge.
