Residents of the Bay Area, CA, how do we address the homeless camps littering the streets of Oakland and surrounding towns?

Before we get started, PLEASE, no political agenda harping, shit posting, trolling, etc. This is something that is on a sharp increase right now in the Bay Area and I'm genuinely wanting to hear other people's thoughts and opinions on this.

The homeless camps have officially reached an out of control level. There is no denying this. Trash and used hypodermic needles litter the streets. Drug use and sales is seen on street corners near the camps. I personally have seen residents of the camps painting graffiti in broad day light. There are unsafe cooking set ups causing explosions and fires putting residents at risk and leaving charred remains for weeks at a time.

What is going on here? How come cities are not cleaning this stuff up? I realize that if the city did conduct some massive eviction/clean up, the residents would just move somewhere else. But what about the trash? Can't that be cleaned up? In many places, I've seen it up to the ankles of people walking around in the camps.

I truly don't know what the non-camp residents are suppose to do? Do we just turn a blind eye and let the trash pile up? Or do we demand action to keep our streets clean and safe?
