kevin bowman is a professional photographer, his subject, old houses, his studio? the forgotten streets of detroit. where home after lifeless, collapsing home, he's documenting what he calls the downfall of his once-great hometown. >> i think it kind of shows what can happen to a society if you don't look towards the future, see what's coming down the road and make changes as necessary. >> reporter: ten years ago he started photographering what had been grand houses in wealthy, thriving neighborhoods but decades of bad luck and lost opportunity have driven out half this city's population. nearly a million people since the 1950s. these are the stark symbols of what was left behind. >> the people here are great, they're hard working. they want to make a difference and they managed to make it through almost everything but individuals can only do some much. >> reporter: for its part, the ty is trying to do something about the urban decay. they've plied for federal funds to help tear down some 2300 of these abandoned homes but it wouldn't make a dent. entire neighborhoo
