We don't have an efficient way to convert ocean wave energy into usable electricity at scale.
open
Global / Unspecified, Global
Wave energy is abundant and largely untapped, but current technology to harness it reliably and affordably lags far behind wind and solar. Cracking this could add a major renewable source to the global energy mix.

We haven't found a way to protect pollinator populations from the multiple threats they face at once.
open
Global / Unspecified, Global
Bees and other pollinators face combined pressure from pesticides, habitat loss, and disease, and addressing just one threat rarely solves the overall decline. A comprehensive solution addressing all major threats together remains unbuilt.

We can't yet build packaging materials that decompose fully and safely without leaving microplastics behind.
open
Global / Unspecified, Global
Many products marketed as biodegradable still break down into tiny plastic particles that persist in the environment for years. A truly safe, fully compostable packaging material remains elusive at scale.

We don't have cheap technology to capture and reuse water lost through evaporation in dry farming regions.
open
Global / Unspecified, Global
In hot, dry climates, a significant portion of irrigation water is lost to evaporation before it ever reaches crop roots. Affordable ways to reduce this loss could ease water stress in agriculture-heavy dry regions.

We haven't solved how to prevent groundwater contamination from industrial and agricultural runoff.
open
Global / Unspecified, Global
Chemicals and fertilizers seep into groundwater supplies over years, often going unnoticed until wells become unsafe to drink from. Preventing this contamination before it happens remains far harder than detecting it afterward.

We can't accurately measure how much carbon forests are really storing or losing in real time.
open
Global / Unspecified, Global
Estimates of forest carbon storage vary significantly depending on the measurement method used, making it hard to track progress on climate goals tied to reforestation. More precise, consistent measurement remains an open challenge.
Citation ID: WS00201
Title: We can't accurately measure how much carbon forests are really storing or losing in real time.

We don't have a reliable way to restore wetlands that have been destroyed by development.
open
Global / Unspecified, Global
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.

We haven't found a way to make solar panel production itself fully environmentally clean.
open
Global / Unspecified, Global
Manufacturing solar panels currently involves energy-intensive processes and some toxic materials, undercutting part of their environmental benefit. A cleaner production process would make solar energy's benefits more complete.

We can't stop invasive species from spreading and damaging ecosystems faster than we can respond.
open
Global / Unspecified, Global
Non-native plants and animals often outcompete local species once introduced, and by the time damage is noticed, removal is difficult and expensive. Faster detection and response systems remain underdeveloped.

We don't have widely available technology to convert agricultural waste into clean energy affordably.
open
Global / Unspecified, Global
Farms produce enormous amounts of leftover plant material that mostly gets burned or discarded rather than turned into usable energy. Affordable, small-scale conversion technology could turn this waste into a valuable resource.

We haven't solved how to farm livestock without contributing heavily to greenhouse gas emissions.
open
Global / Unspecified, Global
Raising cattle and other livestock produces a significant share of global methane emissions, yet meat remains a major part of diets worldwide. A lower-emission farming method that doesn't require giving up meat entirely remains unsolved.

We can't yet track ocean plastic pollution accurately enough to know exactly where it's coming from.
open
Global / Unspecified, Global
Plastic waste in the ocean is well documented, but pinpointing exact sources at a granular level remains difficult, making targeted prevention harder. Better tracking could focus cleanup and policy efforts where they matter most.

We haven't found an affordable way to protect low-lying island nations from being submerged by rising seas.
open
Global / Unspecified, Global
Some island nations face the real possibility of becoming uninhabitable within decades due to sea level rise. Cheap, effective coastal protection or relocation planning remains urgently unsolved for these communities.

We haven't found a scalable way to teach basic coding skills to students in under-resourced schools worldwide.
open
Global / Unspecified, Global
Coding education often depends on expensive devices, reliable internet, and trained teachers, none of which are guaranteed in poorer school systems. Closing this gap could open technology careers to far more young people.

We can't build computer memory that's both extremely fast and extremely cheap at the same time.
open
Global / Unspecified, Global
Faster memory tends to be far more expensive, forcing constant trade-offs in computer design between speed and cost. Solving this trade-off could make faster computing broadly accessible.

We don't have a foolproof way to stop AI chatbots from confidently stating false information as fact.
open
Global / Unspecified, Global
Even advanced AI systems sometimes generate plausible-sounding but incorrect answers, and users often can't tell the difference without checking elsewhere. A dependable way to prevent this remains unsolved.

We haven't solved how to make satellite internet affordable enough for the world's poorest regions.
open
Global / Unspecified, Global
Satellite internet can reach remote areas traditional cables can't, but current pricing puts it out of reach for many of the people who need it most. Bringing the cost down could close a major digital divide.
