How to get bunny to stop chewing?

He chews on everything! I've taken most the cheweable stuff off the floor, but he just finds something new to chew on! i can't leave him in his cage all day, that's cruel, and i will not hit him. I holler at him and he just keeps doing what he's doing, if i stomp on the ground normally he'll stop.. but he does it again in five minutes! Help!?
