Maybe it ISN'T environmentally sustainable. Larry Niven has written 
some sort-of-sword-&-sorcery stories in a universe in which magic 
works by consuming a natural energy source named 'mana'. Mana, like 
many natural resources, seems to come from the earth and is located 
in geographical places. If wizards do enough magic in one place, all 
the mana there will be used us, and magic will no longer work there. 
Magic no longer works in our world because the wizards of previous 
ages used up all the mana that ever was on Earth.

you just said?)
