Manila is one of the world’s five dirtiest cities, but graffiti? That’s not a problem. It’s not that people don’t paint on the walls in the hyper-polluted Philippines capital, because they do. But they do it with a paint that actually eats smog out of the air. The catalytic paint, called Boysen KNOxOUT, reacts with light and water vapor to filter out nitrogen oxides. An environmental scientist interviewed in this BBC video says it can scrub out 20 percent of polluting nitrogen. Manila is deploying the paint in the form of massive murals, which are both beautiful and, because of their size, effective. Eleven square feet of paint-covered surface can absorb as much pollution as a full-grown tree, and these murals are close to 11 THOUSAND square feet. If we could get this stuff into the hands of street artists and taggers, it would be like having an army of energetic teenagers planting trees all over the city all day, every day.

This is incredible!
I am known in some places as Arethinn. I'm 34, Californian, Pagan, faery/sidhe, nerd, library technician (cataloger). What are
little big fae made of? Starlight and glitter... silver lamps of fae-light under hill... the crescent moon and the evening star in the west... sunlit redwood trees and streams... oh, and Severus freakin' Snape. I tend to be sarcastic and introverted and I am not very good at looking like a beautiful, kind, interesting person 'cause, yanno, I am kinda not one. I post a good deal of otherkin-related stuff here, but also reblog photos and fantasy/faerie art, a bit of Harry Potter fanart, and dashes of random. Rah rah Ravenclaw!
