Tomorrow, April 22, is the 40th anniversary of Earth Day. It’s a great time to learn about our planet, how to take care of it and to encourage kids to think about it and take little steps that can make a difference.

So we’re giving away our Erika Knows Green: Water Conservation book free from April 22-23 in the iTunes App Store, to encourage you to spread the green message.

Please download the book and tell your family and friends about it.
