What do the Sahara Desert, Atlantic Ocean, and Amazon Rainforest have in common? Vital, life-sustaining dust! Thousands of years ago, there was a huge lake in the African country Chad. As it dried up, the animals that died in it and became fossils have now turned into dust that moves in a giant cloud across the world. As the dust cloud moves west over the Atlantic Ocean, it helps the ocean make oxygen and softens the impact of hurricanes. Over the Amazon Rainforest, it restores the phosphorus that is washed away by the rain, allowing the forest’s plants to grow and support the ecosystem. At its peak in the spring and summer, the dust cloud can be as heavy as “almost 262 billion basketballs” (23). This dust cloud is incredibly important to the global ecosystem. 

Martha Brockenbrough uses poetic, expressive text that easily gives readers an idea of how the dust cloud works; the trout that eventually becomes dust is “gulping plankton” (5), the dust “soars across West Africa” and “paints the sky” (10). Even though there is little text on each page—nine lines at most—Brockenbrough accurately and clearly describes where and how the dust plume travels and why it is so important to the world’s many ecosystems. By doing this, she emphasizes how the natural world is connected across oceans and continents. Brockenbrough also includes detailed backmatter that explains more about how the dust is created and its impact. Juana Martinez-Neal’s stunning mixed-media drawings bring the Saharan dust plume to life. She uses a combination of realistic illustrations and specks of color that demonstrates the harmony between the dust and the life it supports. The bright, vibrant colors of her illustrations beautifully show the world’s natural diversity. A fascinating book about the importance of dust, A Gift of Dust will make a wonderful addition to lessons and programs about ecology and environmental science.
