for one thing, there just aren't that many of them. there are under 200k hobbyist pilots in the US, and they mostly fly small single-engine planes. it's a problem, but it's pretty far down the list of emissions concerns. see also: two stroke engines in lawnmowers, boats, etc.
- sneak 6y agoLead is an issue not because of the general fact that it is dirty pollution (like two-stroke engines), but because of the precise neurological effects of lead in human bodies specifically. There is a difference between sprinkling sulphur dioxide over an area and, say, plutonium.
- paulryanrogers 6y agoContinued use of leaded fuel over time means it can build up in the environment. Living near an airport now I'm reluctant to eat anything from gardens nearby.
- orange_tee 6y agoTwo stroke might look bad if it is burning too much oil but in terms of health affects it is nowhere near as bad as leaded petrol.
- roywiggins 6y agoThe particulate pollution of 2-stroke engines is really, really bad. https://phys.org/news/2014-05-two-stroke-scooters-super-polluters.html https://phys.org/news/2014-05-two-stroke-scooters-super-poll... (Lead is arguably worse, but only because lead is unbelievably bad for you, not merely very bad for you)
