Why is air pollution in the city constantly growing?

There are more and more cars on the roads, but the streets were designed a long time ago - they weren't built for this kind of volume. Plus there are factories, construction sites, and the population in cities keeps growing, so it's actually getting harder and harder to breathe.

The infrastructure just can't keep up with how fast the city's growing :) When they planned this district 30-40 years ago, nobody expected this many people and cars. Now new neighborhoods are being added, but they're often built the same way - without proper ventilation systems, parks, or greenery. And trees, by the way, are actually a really important air filter, but they get cut down for development.

Plus the factories aren't going anywhere. Even if they moved the plants outside the city, the emissions still get blown around the area by the wind. Construction sites also kick up tons of dust, road work, and asphalt releases all kinds of stuff when it's hot. And the building density itself is a factor - in old cozy neighborhoods with smaller buildings the air at least circulates somehow, but in these modern canyons between high-rises it just stagnates.

Basically, it's a complex problem. You need both more greenery and better public transport and emissions standards. But as long as the population and economic activity keep growing, pollution's gonna lag behind whatever solutions they introduce :( Out at the dacha of course there's none of this - the air's completely different out there.

The main thing is not to think it's just about the number of cars or outdated urban planning :) In reality, most of the pollution comes from industry, which is often located within the city or right next to it, and the wind just carries it all over to residential areas. Plus cities are always warmer because of asphalt and concrete, and that changes air circulation - pollutants get trapped and don't disperse naturally like they do in the suburbs.
