East Hastings in Vancouver.
This is literally what the area looks like on a normal day. Hundreds of homeless people, addicts, and prostitutes wander, each in their own personal hells. Wherever you look in the alleys you will see people shooting up. Needles and condoms litter the ground. It is a post-apocalyptic nightmare made reality. And we leave them to rot. Just heard them all into one area and look away.
