Styrofoam packing peanuts, bubble wrap, and foam are useful during a move, but not for the environment.
To go green on your next move, try using old newspapers to wrap fragile items, and then recycle the paper when you unpack. Wrap pieces of furniture and art with blankets to ensure they do not get damaged during the move instead of packing them in foam. If you must use non-biodegradable packing materials, ask around to see if anyone has any from a past move to give you.
Reusing is always better than buying new––for the environment AND your wallet.
