VISIBLE: In this photo you can see that your attention goes directly towards the two high towers that is divided by a big avenue. You can see many buildings in the back. There is light from the sun but also many clouds. INVISIBLE: Air pollution (smog), the photo was taken from a really tall building, Not a lot of traffic as usual so it was taken at 11am-12pm when its not rush hour. AIR POLLUTION: the big gray cloud we see in the background is actually smog caused by the pollution from all the cars that are in active use. When you´re on the ground you can´t notice this until you have a different perspective. When you get high enough you can see how dense the smog is and think about what we are breathing in. This is how the city pollutions looks like on one of the good days, other days you cant see many of the tall buildings.
