Creating art can sometimes be a noble endeavor, especially when it inspires and gives new perspectives to the observers. But when art does that, AND it's sustainable, now that is truly a wonderful thing. And just recently, some talented artists in Hong Kong teamed up with an Indian-based company to create street art from ink and paint made up entirely of smog. 

Certain parts of Asia have, for a while now, been dealing with air pollution severe enough to have detrimental effects on the human body. According to the WHO (World Health Organization), more than 2 million people die every year as a direct result of polluted air. And as populations increase everywhere, more pollutants are generated and released into the air that we breath. One of these pollutants, in particular, is hazardous to human health. Fine particulate matter, also called PM, causes approximately 9% of all lung cancer deaths around the world, 5% of cardiopulmonary deaths and about 1% of respiratory infection deaths. And as if that weren't bad enough, levels of PM are increasing in Asia.

To bring attention to this current environmental issue, India-based Graviky Labs partnered with Singapore's Tiger Beer to announce the launch of Air-Ink, a series of markers, paint and spray paint made entirely out of car exhaust. Hardware captured the pollutant particles while the cars equipped with them were in motion. So instead of being released into the air, and eventually into our bodies, the particles were purified and processed into black ink and paint. And with these smog-based art supplies, a group of young Hong Kong artists took to the streets, creating art all over the city and in the process, making people aware of a very serious problem the world today is dealing with.

One of the definitions of the word sustainable is, "capable of being maintained at a steady level without exhausting natural resources or causing severe ecological damage." It's a word that we all should think about more often, because being conscious of it will affect us all in the long run. Even now, we're depleting the earth's natural resources like they're going out of style. 

On that note, check out the artwork below. It's all awesome, and even more important — all sustainable.
