Dust may seem inconsequential, so tiny and mundane as to slip below the threshold of thought. Yet within the next one hundred years, life on Earth will be profoundly changed by heat and drought – and that means dust.

In Dust: The Modern World in a Trillion Particles, I argue that dust is a legacy of twentieth-century progress and a toxic threat to life in the twenty-first.

It tells a story of how the relentless drive for profit and power has turned the world to powder. Combining history and science, travel and nature writing, I show how the modern world was made through environmental devastation – and then brushed the consequences under the carpet. From particle air pollution and nuclear fallout to desertification, dried-up seas and melting glaciers, we’ve profoundly altered the planet we live on. The cost to human health – and to the natural world – proves immense.

From the California desert and the Dust Bowl in Oklahoma to the desiccated remains of the Aral Sea and the edge of the Greenland ice sheet, we are shown that some of the planet’s most remote and forgotten places are central to the modern world.

With clarity and insight, Dust: The Modern World in a Trillion Particles helps us see the big ideas found within the smallest particles.
