About Joan Prefontaine
Allergy sufferers may wish to steer clear of this book, unless they like to hear facts such as "you breathe 700,000 of your own skin flakes each day," and "the average child eats 15 or 20 milligrams of dust a day." But many readers will find this book too intriguing to put down, and will relish Holmes's lucid scientific writing, if not all the facts she unearths about bacteria, viruses, dust-mites and other conventionally unsavory topics.
Ashes to ashes, dust to dust. We live covered by dust and one day we will return to it. Billions of tons of dust rise from volcanoes, deserts, oceans, and factories every year. Billions of tons fall to earth again, some from outer space. Industrialized society has been busily changing the components of dust, adding toxic elements that may be lethal over time: mercury, chromium, lead, herbicides, PCBs and pesticides. Holmes makes it clear that pollution knows no borders, and that we cannot isolate ourselves from smokestack emissions in far-off countries. Wind and storms move dust particles all over the globe. Some dusts reflect sunlight and cool the planet. Others, like black soot, soak up heat as they move through the sky. Dusts, like gases, affect long-term weather patterns.
Many of the dusts that travel the earth help keep the planet green and healthy. According to Holmes, fungi "break down a variety of substances, including the dead flesh of plants and animals, and even rocks." In doing so, they release trapped nutrients and enrich the soil. Some Caribbean islands would be bare if it weren't for the dusts of deserts and volcanoes that have settled on their gray rocks, creating lush vegetation.
Cosmic dust creates new planets and solar systems. Holmes writes: "Each star that dies rains more dust out into the galaxy, like a black firecracker. It is this dust of expired stars that will form the next generation of Suns, Earths, and other heavenly bodies." Yet with each generation of stars, the universe, she says, will become dustier. In time it will begin to fade. "Eventually, like an old newspaper in the attic, the worn-out universe will gradually disappear under the thickening dust." (The way Holmes describes it, even such a grim scenario as the end of the universe comes across as intriguing, even a little magical.)
Because this writer has the rare ability to draw from many fields, including astronomy, climatology, biology, natural history and pathology, she offers us a compelling overview of how dust has shaped, and will continue to shape, life on earth. It would be a shame to allow Holmes's book to gather dust, when so much is at stake.
