Nuclear is greener and less polluting per Watt generated than all other forms of energy production we can currently do, including solar and wind, and skyscrapers aren’t too bad either, and planes are so much better than they were. There is nuance in these things but yeah plastic packaging and too many cars are issues, so is unnecessary flying, not having proper recycling standards set up for most plastics produced actually being used on any large scale. But if we had been less afraid of Nuclear energy and gone that route today we would be a lot better prepared for global warming which wouldn’t be as far along, no oil shocks would be as bad, and hell with less of a demand for fossil fuels there would probably be less plastic waste as well.
