Doorways!
George RR Martin in the 90s did a TV movie pilot for a series called Doorways where the protagonists could jump through a portal into an alternative dimension where things were the same but slightly different. This preceded Sliders by about a year (wonder where they got the idea). Anyway one of the plot lines of the dimension they jumped into was that on earth 2 (or was it 3, I haven’t seen it since 1994) they had designed a bug that would solve the earths ecological problems by eating oil based waste. Only the bug spread worldwide eating all the oil, and anything made from it such as plastics. As a result the earth was a much healthier place to live due to no pollution, but we were pretty much living back in the 1800s technologically.
