Nz has good air quality
because we have a low population density,
and our closeness to sea/mountains
plus we also don't have any immediate neighbours.
As NZ grows the air quality will and can get
worse as the population and size,
of our towns grow.
You're right, we are very lucky where we live to have such good air quality. I wonder what we can do to keep it that way when our population starts getting bigger?
