This Green Kids Club books offer children a visit to Hawaii. They can get excited about snorkeling in the ocean where they will see dolphins, turtles, manta ray, crabs, fish of all kinds, and even perhaps a shark. With dolphins and a baby shark helping, the children bring the wrath of the volcano to convince some men not to take the fins of a great white shark. Author Sylvia Medina is a mother and an environmental engineer. She founded Green Kids Club to encourage "Growing up Green." Each of her stories introduces a tough environmental issue such as poaching or habitat encroachment. With the help of talking animals and local friends, the Green Kids manage to get into and out of trouble and learn more about helping the environment.
