Chemical World: Science in Our Daily Lives explores some of the materials—all of which are made of basic chemical elements—that humans use or come into contact with in their day-to-day lives. Some of these chemicals are naturally occurring—clay, mercury, lead. Others have been synthesized by chemists during the past 150 years and used in a bewildering array of products ranging from roof shingles to toothpaste. Many chemical inventions, as well as naturally produced chemicals, have had profound effects on food supply, developing medicines and creating hosts of useful items for modern life. Despite people using both natural and synthetic chemicals with (mainly) good intentions, some chemicals have had unintended negative consequences. Chemical residues have contaminated ecosystems the world over and are compromising the health of many ecosystems, animals and humans. The goal of Chemical World: Science in our Daily Lives is to introduce readers to basic chemistry and chemical history, and to show how chemicals are used for particular reasons but sometimes turn out to be harmful to environmental and human health. It invites readers to take a look at the world around them and ask questions about what’s in their environment and how the things they use and eat every day can affect their own health and the planet’s health.
Going wild. We don't see it as a good thing. And why would we? For most of our time on earth, humanity has been running from lions and other wilderness dangers. We've worked hard to make our local landscapes as safe and convenient as possible. Sometimes that's meant paving over areas that might burst into weeds. Other times, we've dammed rivers for electricity or irrigation. But now pollution, climate change and disruptions to the water cycle are affecting the world in ways we never anticipated. What if the new key to making our lives safer (and even healthier) is to allow the wilderness back into our cities?

Until a few hundred years ago, people were embarrassed to buy bread in a store. Families took pride in making almost everything they owned.
