Changing with the times: See how Future Problem Solving environmental topic-related challenges evolve through the decades.
For more than 50 years, Future Problem Solving students have taken on the challenges shaping our planet. Long before they dominated headlines. From climate and clean water to biodiversity and human health, each generation has been asked the same question: What happens next and how do we solve it?
This Earth Day, we’re looking back at the issues students have explored over the years and the patterns that emerge. Because the future doesn’t arrive all at once. It builds over time. And the students working through these challenges today will be the ones shaping what comes next.
AIR | Preserving the climate, seeing what’s next
Future Problem Solving students have tackled the biggest threats to our air before they dominated global conversation. From acid rain to ozone depletion to climate change, each generation has been asked the same thing: What happens next and how do we solve it? The challenges evolve. The mindset doesn’t. Our students don’t just study the future. They practice solving it.

WATER | Ensuring clean water: Solving what sustains us
For decades, Future Problem Solving students have taken on one of the most complex challenges on the planet: water. From shortages to ocean ecosystems to water quality, the questions have evolved but the urgency hasn’t. What’s changed? The stakes. Clean water is no longer a distant concern. It’s a defining issue of our time. Our students don’t just learn about it. They work through solutions before they’re needed most.

LAND | Preserving the climate: Land under pressure
Future Problem Solving students have explored how land is used, changed, and pushed to its limits. From shrinking forests to rising seas, the pattern is clear: The more we alter the planet, the more complex the consequences become. And sometimes, the solutions raise new questions. Like how far is too far? Our students don’t just study environmental change. They wrestle with what comes next.

LIFE | When nature changes, so do we
For over 50 years, Future Problem Solving students have explored the connections between ecosystems, species, and human health. From endangered wildlife to toxic materials to biosecurity, one idea keeps resurfacing: Nothing exists in isolation. When ecosystems break down, the impact doesn’t stay there. It reaches all of us. Our students don’t just study these connections. They learn how to navigate them. Because the future of human health depends on the health of everything else.

RELATED IMPACTS | What happens after we create, consume, and power the world
Throughout the decades, Future Problem Solving students have explored what happens after innovation. Waste doesn’t disappear. Energy isn’t free of tradeoffs. And solutions don’t scale without systems to support them. From nuclear waste to e-waste, from solar energy to the cost of mining, one truth keeps surfacing: Every decision creates ripple effects. Our students don’t just solve the problem in front of them. They learn to anticipate what comes next. Because the future isn’t just built on ideas. It’s built on the consequences of those ideas.
