Germs, microbes, bacteria--these days those words are fraught with fear and uncertainty. But they're not all bad. In fact, most of them make life and nature possible. Christian Borstlap's playful, boldly colored illustrations and cheerful text will help kids understand that microbes are everywhere--in our noses and tummies, in the food we eat, in the air we breathe. From the world's largest organism in Oregon's Blue Mountains, to the bacteria that started life on earth; from microbes that help recycle plastic, to yeast that makes bread taste good--this book shows the incredible diversity of these tiny beings and how they affect every aspect of our lives. Borstlap uses both science and humor to demystify a potentially scary subject, and closes with double-page spreads that are packed with information to satisfy the most curious readers.
