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.

Humans generate an incredible amount of trash. In Canada alone, 35 million tonnes of food is wasted every year. That’s a lot of energy spent growing, processing, packaging and delivering food that ultimately goes uneaten — and all that waste creates a lot of greenhouse gases. To fix the climate, we have to redefine our relationship with waste; that means doing more with what we already produce. In this episode, we head up into space to see how astronauts deal with their waste, travel to a facility to learn how food scraps are being transformed into biogas and explore how the concept of circularity could help us manage our resources better. It’s time to face the waste.

As we start to feel the effects of climate change, it’s clear we need to find ways to adapt our communities and lighten the impact on the planet. It can be tempting to just start over somewhere fresh — to build a fully optimized city that’s decked out with the latest technology to be sustainable and efficient. But as we’ve seen in one smart city development after another, these projects often fail to live up to the hype. It might be time to rethink what a smart solution actually looks like. In this episode, we learn about two companies that are harnessing the power of artificial intelligence to retrofit what already exists. By optimizing heating and cooling systems and re-tooling public transit, these two ventures are already helping shrink the carbon footprint of cities. It’s a good reminder of the power of incremental change.

Humans are wired to want more. More time, more resources, more money. But what if we could do more with what we already have? When we innovate for resilience, we often think big — bypassing solutions in our own homes. Today, we’re looking at the design of objects (like electric cars and heat pumps) and discovering their purpose can go far beyond the original intent. As we move to more sustainable forms of power, energy storage is becoming increasingly important. Here, we explore novel ways we can address energy intermittency in the future and also look back in history for lessons in making those kinds of changes.

Trees have an incredible ability to absorb carbon — which means protecting, planting and restoring forests are a (relatively) easy way to address global warming. Climate change, however, is making it more complicated. Our forests are (quite literally) going up in smoke, which has far worse consequences than one might expect. In this episode, we explore the role forests play in carbon sequestration, how increasingly intense fires are threatening to turn them into a carbon bomb, and how technology (think drones, satellites and lasers) can assist in our replanting and conservation efforts. The forests have helped us, it’s time to help them.

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.

As the effects of climate change trigger record-breaking rainfall and flooding, cities from Montreal to Mumbai are re-thinking how urban design can keep inhabitants safe from natural disasters. Kongjian Yu, a landscape architect based in Beijing, has a counterintuitive idea. Instead of fighting water by building more dams, sewers and pipes, he proposes we let it in, designing nature-based infrastructure that can absorb run-off. His principles have been adopted by the Chinese government and implemented in hundreds of municipalities. Could this nature-based approach help us adapt to a changing climate?

The wildfire that devastated Fort McMurray in 2016 burned more than 579,000 hectares of land, drove 88,000 people from their homes and caused nearly $10 billion in damages. It’s often seen as an outlier, a freak natural disaster. But extreme wildfires, like those that tore through Los Angeles earlier this year, are becoming more intense and harder to control. “We all saw the smoke, and too many of us have seen the fire,” says John Vaillant, author of Fire Weather: The Making of a Beast. “Weather is different now, and fire is different now.” Hotter, drier weather is turning our forests into kindling, and emergency responders are struggling to handle our new reality: intense, unpredictable fires fuelled by a changing climate. In this special episode, host Manjula Selvarajah sits down with Vaillant to better understand how we got here and to see if there is any way out.

Featured in this episode: 

John Vaillant is a Vancouver-based author and freelance journalist. His latest work, the Pulitzer Prize–nominated Fire Weather: The Making of a Beast, chronicles how the 2016 Fort McMurray wildfire turned entire neighbourhoods into firebombs and destroyed 2,400 homes and businesses.

Modern medicine has a dirty secret. While plastics have revolutionized healthcare, research increasingly shows that they’re also making us sick. Items such as PPE, syringes, gowns, IV bags and protective wrappings have allowed for a higher standard of sanitary patient care that vastly reduces the risk of cross-contamination. But all that plastic is adding up. Nearly a third of healthcare waste is plastics, and a report on 110 Canadian hospitals revealed the combined waste adds up to 87,000 tons of waste each year. These items break down into microplastics, which accumulate in our bodies and contribute to neurodegenerative, reproductive and overarching health problems. But what will it take to reimagine healthcare without plastic?

Featured in this episode: 

• Journalist Susan Freinkel is the author of Plastics: Toxic A Love Story, a book that traces the history of plastics through eight different objects, from the Frisbee to the IV bag, and examines how plastic negatively affects our lives.
• Dr. Ted Schettler is a physician and expert on the health risks of plastics and phthalates. He’s the scientific advisor at Health Care Without Harm, an organization that has dedicated more than 30 years to reducing healthcare’s environmental impact, including the removal of mercury from medical devices.

Extreme heat waves are anything but normal, but they’re quickly becoming the new reality. The 10 hottest years on record have all happened in the last decade. And because temperatures in urban centres can be 10 to 15 degrees Celsius higher than surrounding areas, cities can be dangerous places to be when the mercury rises — particularly for the elderly, those with pre-exisiting health conditions as well as poorer populations who lack access to air conditioning. “Heat has a way of going through the city and finding those who are the weakest,” says Eleni Myrivili, the United Nations’ global heat officer. “It’s a very unfair climate condition.” In this episode, we explore the growing risk posed by heat and what could help us adapt to a hotter world. 

Eleni Myrivili is the United Nation’s first-ever global chief heat officer. An anthropologist by training, Myrivili understands how heat waves discriminate against older, less-wealthy and under-served demographics. Before being named to her UN post in 2022, Myrivili was Athens’ heat officer, where she coordinated the capital’s response to heat waves and helped renovate an ancient Roman aqueduct to bring water into the city.

Experts are calling antimicrobial resistance the silent pandemic: Each year, AMR is responsible for more than a million deaths around the world. It’s a threat to our health that’s been exacerbated by the very medications used to treat it. This problem has been growing for decades, and healthcare practitioners have responded by developing new antibiotics. “And then,” says Dr. Scott Weese, a global expert in antimicrobial resistance, “we started running out of antibiotics.” To address the rise of drug-resistant pathogens, we need to examine how we use these medications to treat disease in both humans and animals, says Weese. The question is, how can we safeguard the life-saving drugs we have — while also protecting the health of all creatures on this planet?

Featured in this episode: 

Dr. Scott Weese is a veterinary internal medicine specialist, chief of infection control and director of the Centre for Public Health and Zoonoses at the University of Guelph’s Ontario Veterinary College.

The hotter it gets outside, the more we use air conditioning, and the more we use air conditioning, the hotter it gets. AC units and refrigeration combined adds up to 10 percent of global greenhouse gas emissions. But how can we solve this cooling paradox? Building on last episode’s conversation with the UN’s global chief heat officer, host Manjula Selvarajah meets the experts harnessing novel innovations to keep cities and people cool — from massive infrastructure projects using ice-cold lake water to microscopic solutions to get rid of that sticky, sweltering humidity.

Brain-computer interfaces (BCIs) have been allowing humans to control objects with their minds for nearly half a century. But in recent years, thanks partly to advances in AI, the technology has evolved dramatically; wearable and implantable devices are now being used to restore speech and movement to stroke survivors, alleviate depression and treat pain. While companies like Elon Musk’s Neuralink grab headlines, a somewhat quieter revolution is happening in Canada, where researchers are using BCI to help a historically underserved population: disabled children. In this episode, we explore BCI’s potential to transform medicine, the knotty ethical questions at its core and how the tech might just bring us closer together.

The fashion industry has its fair share of dirty secrets, but one of the lesser-known is how much it pollutes our waterways. Every year, garment factories use as much as 2 trillion gallons of water to dye clothes, and most of that water, now filled with harmful chemicals, flows untreated into rivers, streams and lakes. Those pollutants can turn rivers black, harm marine life and cause cancer. Macarena Cataldo, a chemical engineer based in Vancouver, has come up with an ingenious way to remove these contaminants before they even reach the water. In this episode, Cataldo talks to Manjula Selvarajah about the global water crisis, how her technology works and efforts to get major fashion brands to change their ways.

Featured in this episode: 

Macarena Cataldo is the CEO and CTO of Viridis Research, which she co-founded in 2019 to solve various global water challenges by eliminating pollutants from water sources. She has a PhD in chemical engineering, and has spent more than 15 years applying electrochemistry to drinking and wastewater treatment working with the European Space Agency, the Metropolitan Water Company of Turin and others.

There’s no denying that technology plays — and will continue to play — a critical role in addressing the climate crisis. But could super-intelligent AI actually solve the problem for us, as several tech billionaires claim? Or is this over-reliance on speculative technology simply a way to distract us from tackling big, real-world problems. Manjula Selvarajah sits down with astrophysicist and author Adam Becker to separate the hype from reality.

There are few neurodegenerative diseases as devastating as Huntington’s. It’s sometimes likened to having Parkinson’s, ALS and Alzheimer’s all at the same time, with symptoms that include progressive motor dysfunction, cognitive decline and behavioural change. It’s also hereditary — if a person has the faulty gene that causes the disease, there’s a 50 percent chance their children will have it, too. In the fall of 2025, however, scientists announced that, for the first time, they could reduce the progression of Huntington symptoms using a new gene therapy. While that clinical breakthrough came with several caveats, it also heralded a possible new paradigm for drug discovery. In this episode, we explore how this innovative therapy works and what it could mean for the treatment of other rare diseases. 

Featured in this episode:

Rachel Harding is an assistant professor in the department of pharmacology and toxicology at the University of Toronto and a principal investigator at the Structural Genomics Consortium. Her work on Huntington’s disease has been recognized with major early-career awards, highlighting both scientific excellence and the potential patient impact of her research program.

The housing crisis is fundamentally a health problem. Decades of research show that people experiencing homelessness spend twice as long in the hospital, cost the healthcare system double and have a life expectancy half that of the average Canadian. In this special episode of Solve for X: Innovations to Change the World, recorded live at a MaRS Morning event, host Manjula Selvarajah sits down with primary care physician Dr. Andrew Boozary to discuss a radical shift in Canadian medicine: treating housing not just as a social service, but as a critical medical intervention. As founding executive director of UHN’s Gattuso Centre for Social Medicine, Boozary shares data-driven insights from his initiatives there: prescribing nutritious food boxes, the launch of Ontario’s first hospital-based homelessness and eviction program and, most famously, the establishment of Dunn House, a permanent supportive housing model that’s proven to be both effective and scalable. Together, Selvarajah and Boozary explore what it takes to dismantle bureaucratic sludge, cut through systematic fragmentation and build a healthcare system rooted in human dignity.

Dr. Andrew Boozary is a primary care physician and the founding executive director of the Gattuso Centre for Social Medicine at University of Health Network (UHN). At the forefront of health equity and public policy, his work focuses on integrating social determinants of health — such as housing, income and food security — directly into patient care. Boozary has spearheaded pioneering social medicine models including Toronto’s modular permanent supportive housing project, Dunn House, establishing crucial healthcare interventions that drastically improve health outcomes while reducing healthcare costs. In 2026, he received a Governor General’s Innovation Award for developing Dunn House.
