The Matrix: There is no Clean Air Act

In The Matrix Reloaded movie smokestacks belch NOx, SOx, VOCs, mercury and heavy-duty particulate matter. You can see many stacks spitting black smoke. Plus, the highways are clogged with huge fume belching vehicles.

Clearly there is no Clean Air Act in the movie world of The Matrix. If there is no Clean Air Act, then wouldn't the inhabitants get asthma? And if you get asthma in the Matrix, wouldn't you get it out of the matrix? Neo is already blind at the end of the trilogy. Imagine him being asthatic too.

So would you need an inhaler when you are in the matrix?
