Patience running thin

What am I supposed to do to make my situation right?

I live in a building without AC, and a single window for my entire apartment. Without fail, within half an hour, someone is smoking cigarettes, meth, or setting a literal fire in the alleyway besides my apartment.

I’ve yelled at people to cut it out, I’ve called the non-emergency line, I’ve tried talking directly despite the rather unsafe proposition that it is, and yet three years into living here and never once has it ever stopped. I am devastated every time there is a heat wave because I am forced to swelter inside my 8th-floor apartment where all the heat rises. I don’t know what to do and I lose my mind. 5 in the morning, trying to get cold air into the apartment so we can enjoy the morning? Meth. 2 in the afternoon trying to beat the heat? smoke. 10pm at night and wanting fresh air to sleep? A literal campfire being started. The fire dept has already pulled out someone who set the greenery on fire in my alleyway, and all their belongings burned, and the only thing I could really care about was the fact that it smelled like smoke for a week when I tried to get any kind of air inside my apartment.

I’m so lost on how to actually improve this because I cannot afford moving to some other apartment, and I just am so lost. How do I even improve this? I want to have empathy and help the homeless but it gets harder and harder to have patience when my basics like sleep and even spending an afternoon in my apartment are disrupted
