Solve for X: Innovations to Change the World MaRS Discovery District

We’re facing a global ecosystem crisis. Within the last 50 years alone, wildlife populations across the world have declined by a shocking 69 percent. But technology, with help from citizen science, is emerging as one of wildlife’s greatest allies. In this episode of Solve for X, we explore how remote sensing, robot boats and DNA analysis could revolutionize wildlife preservation, offering hope for everything from insects to whales.

Climate change is putting many of the foods we love at risk. Add in rapid population growth — the planet will be home to 9.7 billion people by 2050 — and it’s clear we need to reimagine how we feed ourselves. As food security expert Leonore Newman says, “we are running short on planet.” But is society ready for replacement proteins and lab-grown meats? Whether it’s cell-grown salmon or chili lime crickets, the plate of the future is going to look a little bit different. In this episode of Solve for X, we discuss the revolution in what we eat — and why it’s as much about technology as it is about safeguarding our planet’s future.

From Wi-Fi to power stations, roads to pipelines, our infrastructure is stressed. Built for a climate that no longer exists, our systems are failing at an increasing pace. But to fix what’s broken goes beyond structural repair — we also need to address the inequities baked into our infrastructural systems and injustices from past developments. Amid these challenges, we have the chance to reimagine the future of infrastructure for a better world. On this episode of Solve for X, we sit down with Deb Chachra, author of the new book How Infrastructure Works: Inside the Systems That Shape Our World, to rediscover the hidden beauty of infrastructure and how we can harness the collective power these systems bring to our lives.

The future of the automobile is electric. Yet the surge in electric vehicles raises critical concerns regarding battery creation, disposal and recycling. What will happen once all those cars reach the end of the road? In this episode of Solve for X, we address the environmental footprint of EV batteries, confront the challenges posed by the existing regulatory landscape and highlight opportunities for second-life applications. It turns out that batteries are capable of more than you might expect, and can teach us a lot about how to design for the future.

Wastewater, the world’s dirty (not so little) secret, consumes nearly 3 percent of the global electricity demand. It’s a staggering statistic, and yet much of what actually happens with wastewater remains a mystery. Treatment plants typically purify water by infusing it with oxygen, creating an environment where bacteria can break down waste. But without proper sensors or data, the method is incredibly energy-intensive. Plus with an influx of unregulated chemicals, our waste streams are becoming more toxic and harder to clean. In this episode of Solve for X, environmental microbiologist Patrick Kiely shares his unusual solution that harnesses the power of bacteria to help solve our wastewater problem. Unpleasant yet fascinating, Kiely’s work offers a glimpse into what it takes to clean our water and why treating wastewater is the next big climate problem.

The next pandemic — it’s a question of when not if. Climate change is shifting the patterns of how and where diseases spread, and our insatiable love of travel means that viruses are now showing up in places they’ve never been before. Forecasting future outbreaks is becoming increasingly complex. But as infectious disease specialist Kamran Khan explains, this is where AI can help. Machine learning algorithms can detect patterns in data, model risk and project outcomes — and unlike humans they can work 24 hours a day. In this episode of Solve for X, host Manjula Selvarajah sits down with Khan to explore the connections between infectious disease and climate change — and how we can best harness the technology to help us prepare.
