Running out of wheat - the scientist racing to fix it

Our growing population has a huge number of impacts, but the simplest and most pressing is that we have more mouths to feed than ever before. At the same time, though, climate change is threatening farmland worldwide. That means crops like wheat, which account for 20% of daily calories consumed worldwide, are plateauing. Enter: Richard Trethowan and the Plant Breeding Institute. Richard and his team are working on something called hybrid wheat, which will be more robust and productive than the regular plant. They’re trying to make food that’s healthier, easier to grow, and that will feed more people. Richard explains why we’ve never been able to make hybrid wheat before, why it’s so crucial to the future of our planet, and how over a century of forward-thinking research has laid the foundation for the work he’s doing today. +++ The Solutionists is a podcast from the University of Sydney, produced by Deadset Studios.
