    Warn about how plastic (especially single-use) is a major pollutant, with microplastics managing to get into our organs with long term consequences we are yet to grasp.

    It did push our technology and way of living forward, but at what cost?

      You’d be the crazy manbearpig dude. Nobody would listen to you. How would anyone be able to persuade the people?

      That wouldn’t work because you’re a single person fighting against the same companies that finance climate change denialism. Hell, between understanding that leaded gasoline was harmful and banning it were at least 20 years

        Yeah but the OP question isn’t asking what you would do, but rather what you’d change. If the question was about what people would do, half these answers have a lot of explaining to do.

    I’d go hunt down Ronald Regan at about age 30 and empty an entire magazine of .45s into his dome while he slept.

    Depends on time travel method and how would it affect reality (would it create a new timeline or replace the one we currently live in?).

    I would prevent Lewis Powell from authoring the document that outlined how to capture the courts and put us under the control of unelected judges.

    I’d go back and write a book with just enough truths to cement myself as a soothsayer. I’d then warn of wars, eco disasters, pandemics, natural disasters. Then I’d invest some money in some good places and make sure it made it to my kids after I’m gone.

    I’d invent the printing press during the classical era and watch what happens from there. I guess the folks at Carthage would also enjoy knowing about paper making, better wind-powered sails for ships and to be on the lookout for those “Romanes”
