Air pollution is getting serious and inevitable in China, and there is no escape, even your digital space. We collaborate with China’s major portals to hijack the screens of users with smog, the level of smog is tracked by their location and live air quality index to make them experience the same situation outside, yet urge them to take action and join Earth Hour’s project to fight against smog. Zero media budget with supports of many major portals and huge sharing on social media.
