Part of the nonfiction Orca Footprints series for middle readers, this book examines the good and the bad of the chemicals we come into contact with in our daily lives. 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. 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. Chemical World: Science in Our Daily Lives 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 health of the planet.
