It shouldn't be necessary to abandon aviation technology entirely. I'm sure there are a lot of optimizations that could help reduce the number of flights in the air for military, passenger, and freight/cargo as well as advancements in the technology that would make the planes in the air even less harmful. While I do think we'll need to face some lifestyle changes, I don't think extremes like giving up cars for horses, abandoning aviation, or going back to candles and fires for lighting and heating are needed. We can do better and still enjoy the benefits of technological advancements even if the way we enjoy them changes.
