I read a lot of sci fi in the '60s and '70s, including short stories, often in anthologies. I remember a fairly humourous one with a bit of an environmental message in it, I thought. Someone had invented a new improvement to the vacuum cleaner...a machine that made dirt and dust simply disappear. After a certain period of years, it suddenly all re-appeared in great heaps. You couldn't tell if the people at the receiving end of the dirt found a way to zap it back to the senders or if the dirt machine was simply forwarding the stuff into some future period. I'd like to read this again as I thought it was a good analogy for the pollution and problems we simply dump into the future and which will come back at us in volume and in ways that are overwhelming.
PS general web searching has got me nowhere in looking for this.
