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 revo…

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 me…

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…

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 w…

Jessica F. Green was among 400 Canadian climate scientists who called for the government to scrap a proposed tax credit for carbon capture last year, claiming it would underwrite the oil and gas industry. Yet policy is a key component to a successful transition away from fossil fuels — and we need regulation. In this special episode of Solve for X,…

What will it take to get to a world where we have all the energy we need — without the emissions, smog and other climate impacts? The shift requires a rapid draw-down on carbon-based fuels and the use of energy storage technologies. And while lithium batteries have been instrumental in the transition, supply chain and sustainability issues are of i…

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…
