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.

Featured in this episode:

• Lenore Newman, director of the Food and Agriculture Institute at the University of the Fraser Valley, is an expert in food security and technology and holds a UFV Research Chair in Food and Agriculture Innovation.
• Preeti Simran Sethi teaches sustainable food systems at the University of Gastronomic Sciences. She’s also the author of an award-winning book on agrobiodiversity, Bread, Wine, Chocolate: The Slow Loss of Foods We Love.
• Journalist and author Larissa Zimberoff explores the evolving relationship between food and technology in her work. Her book, Technically Food: Inside Silicon Valley’s Mission to Change What We Eat, delves into the transformations in our diets and the startups driving this shift.
• Darren Goldin is a co-founder of Entomo Farms, an insect-based farming company that produces cricket flour, cricket powder and insect protein. He’s also the vice president of farming operations, overseeing the three barns on Entomo’s property.

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.

Featured in this episode:

• Deb Chachra, professor of engineering at Olin College and author of How Infrastructure Works: Inside the Systems That Shape Our World. Her work spans across multiple disciplines, including engineering education, gender issues, materials science and the intersection of technology and culture.

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.

Featured in this episode:

• Patrick Kiely is the CEO and founder of SENTRY, a real-time monitoring biosensor system for wastewater treatment. With extensive training in environmental microbiology, his unique knowledge of bacterial growth across diverse environments forms the basis for advanced decision-making in water and wastewater technologies.

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.

Featured in this episode:

• Kamran Khan is an infectious disease physician and founder and CEO of BlueDot, a startup that has created a tool that maps the spread of infectious diseases. BlueDot’s AI software uses natural language processing to interpret global health outbreak reports, integrating this data with flight patterns, demographic statistics, and human verification processes to alert and monitor disease risks worldwide.
