>Diesel is still a dirty fuel and has done a lot of health damage in Europe. Gasoline is also a dirty fuel that does a lot of health damage, but the particles in the exhaust are much smaller and less visible, so people mistakenly assume it's cleaner and better than visible Diesel smoke. Gasoline is arguably worse, since the tiny invisible particulate matter in the exhaust can stay airborne much longer than the larger, heavier particles in Diesel exhaust.
