Brockenbrough, Martha. A Gift of Dust: How Saharan Plumes Feed the Planet. New York: Alfred A. Knopf, 2025.
I am a fan of nonfiction picture books. They expand my general knowledge, providing a relaxing way to spend a few minutes of free time in the day. I like to leave one out by a comfortable chair, so I can sit down with a cup of coffee and let my mind wander away from the tasks of the day.
Did you know the dust blown from a dried up African lake contains diatomite – fossilized remains of algae – that adds iron to the oceans, which enables the water to absorb extra carbon dioxide and turn it into oxygen? Did you know the cloud of dust from northern Africa can be up to two miles thick and provides phosphorus that replenishes the soil of the Amazon Rainforest? Facts like these remind me of the vastness and complexity of the natural world. They fill me with wonder and curiosity and take me away from the everyday chores of life.
This nonfiction picture book combines all the best features of the genre. Beautiful full-page coloured illustrations by Juana Martinez-Neal set the mood for information arranged on short lines of text in a way that enhances comprehension and creates a smooth flow of information. Additional information is provided at the end, along with a list of sources for further study. Wonderful as a read-aloud, A Gift of Dust is highly recommended for readers 5 years old and up.Â
