It’s a wonderful thing to encourage your children to think about the environment. Children absorb information easily and take it to heart. Reading to them is a great way to encourage them and teach them about the environment.
The challenge can be finding books that will entertain them without seeming like a lecture. Children love to learn, but they get bored if things are above their level or not fun.
The Lorax is one story with an environmental message that has long been popular. My daughter went through a phase of asking for that one almost nightly. Gumfounded is a more recent book, and a bit more direct to children’s experience.
My children are young yet, so I don’t have any experience with children’s and young adult novels with an environmental theme. But if you can keep your child interested in reading as well as in helping the environment, you’ve helped them to understand what can be a complex topic.
