It’s easy to take the air for granted. Although it’s always around us, we don’t often give it much thought.We can’t see, smell, or hear it, but we can certainly feel it move—and that breeze you feel on a windy day is part of a larger air current circling our planet and bringing us all kinds of weather.Our air gives us life, and it makes up the atmosphere that protects us. And because everyone here on Earth shares it, it’s important to take care of our air. With striking art and an expressive text, G. Brian Karas brings our air into focus and will give readers a new appreciation for this precious substance.
