even if the materials used aren't so enviro freindly it is enviro freindly to use up what we have instead of make more 'stuff' even stuff that in the long run may end up being not so great, like plastic. but, its here. its not going away. it takes energy and enviro cost to recycle it or get something else that will work. use it! when it has truly reached the end of its useful life dispose of it in the most responsible way possible.
