> What nastiness are we subjecting ourselves to today? People have already listed a lot of true answers and a number of speculative answers (also likely mostly true, imo), but I'll toss in that we use two-stroke engine leaf blowers and lawn mowers everywhere—mostly right outside our homes—and it's absolutely bonkers. Massive amounts of NOx, PM2.5, etc. We spent all this time and money cleaning up our cars (which are still pretty bad), but then run these tiny things that are far worse, right where we live. I'm willing to bet the noise pollution of them + traffic has a significant negative effect on our health too, but in terms of localized air pollution, the emissions from leaf blowers running a few times week across the street from me easily trump that from all the cars driving past my house. Hoping electric leaf blowers get good and gain popularity.
