The creative ways Chinese activists protest pollution

Public payphones don’t usually ring. So when one started buzzing in Beijing recently, people picked it up. On the other end of the line were residents of Huludao, some 400km away. All had the same story. The city’s factories were polluting the air. Some nights it smelled of chocolate; other nights, of chemicals. Most people kept their windows shut, yet they still struggled to breathe. The government refused to act, said residents. So some started calling the payphone.
