These are a few books centering natural resources/conservation that I've really enjoyed reading:
Spring After Spring: How Rachel Carson Inspired the Environmental Movement by Stephanie Roth Sisson
Our Planet! There's No Place Like Earth by Stacy McAnulty
Around the House That Jack Built by Roz Abisch
A Planet Like Ours by Frank Murphy & Charnaeie Gordon
The Rescuer of Tiny Creatures by Curtis Manley
Not sure on the grade levels. Hope this helps!
