  So… are you saying the air inside a city park isn’t better at all?

    They were talking about CO2 which is what the algae tank is about.

    Trees have other benefits around filtering pollutants that affect air quality such as sulphur dioxide and nitrogen dioxide. Also the shading effect reduces ozone accumulation as well as generally helping reduce the urban heat island effect (which in turn reduces the amount of air conditioning needed, even a small amount saves a lit of energy and reduces pollution from power stations).

    City parks have clean air partly because of tree but also because youre away from roads and buildings so further from car exhausts and chimney stacks. The concentration of pollutants in wide open spaces is lower because the wind can move it around more easily, and there isn’t a pollution source directly near by. Tree and grass do help too.

      Amazing answer, thanks a lot!

      Dunno what i’m getting downvotes for

        I think it’s because they mentioned trees improve air quality right there in their comment, and then you responded like you didn’t read it

      I wish my garden was big enough for trees. There are quite a few trees in a park behind our house though, my wifi might just about reach the park too. A better access point would reach it easily.

      Have wondered if there might be other options for shade. Perhaps some kind of vines on a trellis. But then sometimes you don’t want the shade.

    I think there is a difference between air quality (pollution) and co2 levels.

      Cool they you think they but there are not walls that prevent air from mixing.

        I mean conceptually, not physically like between a park area and a road.

    To be fair, I think it’s important to make a distinction between a city park, and a handful of trees lining a busy street.

    It is, because of the humidity, temperature and also they remove air pollution

    CO² isn’t want you should be concerned about with air in a city anyway, its the other emissions like particulates. Just being further away from busy roads reduces that significantly so the park air would be better.

    Probably not a statistically significant difference since wind is a thing.

  From the top of my head, they also help manage storm water by filtering rainwater into the aquifer, while also lowering flood risks, provides habitats for plants, insects, birds, and small animals while also being a natural sound barriers, which reduces noise pollution. All of these together greatly increase mental health for everyone too
