How microbes are vital for life on Earth, and may even help save the planet

Although we can’t see them with the naked eye, the Earth is populated by vast numbers of tiny living organisms such as bacteria, fungi and viruses. Collectively, these organisms are known as microbes, and they have existed on the planet for billions of years.

But what role did they play in the origin of complex life, how have they stuck around for so long and how can they help us shape a healthier future for the planet?

In this episode, we speak to science writer and author Peter Forbes about his latest book Thinking Small and Large: How Microbes Made and Can Save Our World.

He tells us the role microbes played in the evolution of multicellular life, their deep importance to the world’s ecosystems and how they may help us to produce the food, fuel and materials of the future.
