The unfortunate thing about 'green consumerism' is, its still consumerism. One thing many of us could do is slow down on buying so much shit. Instead of buying a Prius, look after the car you do have, drive it less. More energy is spent manufacturing a car than it might expend during its lifetime.
You could apply this to skate stuff. Use your stuff until its spent. Patch up your shoes. Repurpose your decks (make cruisers out of them), ride your wheels and trucks until they can't be used anymore or pass them on to someone who will get more life out of them.
