The topic of climate change regarding temperature is one thing. But the topic in the media HARDLY ever covers the fact that the air quality is shite. Especially in cities and sub-urban areas.

Lichen is a good indicator of good air quality. It thrives in good air quality. You see lots of it in rural parts.

I live on a main road. When I clean the outside of my window it is always black soot on the tissue. That's just particulate matter. All the other shitty gases alongside CO2 and monoxide making for poor air composition.

So poor quality won't have a good effect on us.

We should just have good ole nitrogen, Oxygen, Argon and a bit of CO2 for plants.
