Except that people don't always recognize it and end up drilling holes in it or sawing through it

Don't forget about when it's time to un-make it.

Tearing down old building or tiles containing asbestos is also a huge issue.

It’s supposed to be it tends to get brittle and fracture creating airborne shards that you can breath in but your body can’t break down and that continuously damages the cells leading to cancer.

Any time you disturb it theres a problem

CSR, if I recall correctly

You can absolutely get high octane ethanol-free gas; there's a place near me that sells it. I know that a lot of people with motorcycles use it, because inline four cylinder motorcycle engines tend to be high compression, and motorcycle people tend to be almost religious about not using ethanol. (Which is unnecessary; assuming your motorcycle is fuel injected, the only risk with ethanol is storage for several months at a time with a full tank of gas. If you do that, then you're going to end up with water in your gas, because ethanol is hygroscopic. As long as you keep riding regularly, or empty your tank and run the motor dry before storing it for more than a month, you'll be fine with ethanol in your gas.) I know of at least once place near-ish to me that sells 110 octane ethanol- and lead-free racing gas. Ethanol-free high octane fuels tend to be about 25-50% more expensive than fuels with ethanol.

Avgas is another story. The odds are pretty good from what I can tell that any prop airplane is going to need gas with tetraethyl lead. To me, that sounds like a good reason to remove them all from service in favor of jets, but I think that jets have a higher stall speed, which can be a problem, esp. in backwoods areas.

(Jet-a and jet-a1 are kerosene derivatives, and don't have lead.)

If you want a sad rabbithole, look at the cancer rates around small airports, which are often much closer to where people live.
