This is a smog eating billboard. It's been coated with a specialized resin that attracts nearby air pollutants and converts them into oxygen when exposed to direct sunlight. The billboard generates the same amount of clean air as 30 trees every 6 hours and it can function for up to five years.4yr ⋅ ILikeY0da ⋅ r/interestingasfuck
