Dr. Seuss is always a good read! This book is a great example of seeing things from a different perspective. The Lorax is trying to look out for the animals and trees and protect them, while the Once-ler sees how the business is growing and how many people want their products that they are creating using the trees. I think this story would be a great way to show that their are different perspectives and they both could be right in their own ways. For older students they could look at the different perspectives of the characters and create a list of ways that each are correct or incorrect.
