Is it pointless to clean my property?

Its hard to explain the reason but i'm limited to what can be thrown in a trash bin. I've tried other things but this is literally the only option i have. The previous owners left massive amounts of trash, a lot of really big stuff that can't be thrown out, theres like 8 refrigerators and a couple cars. I can throw away the smaller stuff which there is lots of, I just don't know if there is any point when all the large stuff has to stay for possibly years and it'd be easier to take it all together.

Around the house is kept very clean but theres 5 acres that I don't spend a lot of time in where all the trash is.
