Smog monitors of the world unite! Marxism meets ozone science in awkward Chinese academic paper
Thesis by environmental science students raises concerns over ideological controls on campus

The Communist Manifesto is silent on greenhouse gases but that hasn’t stopped a group of Chinese students from linking Marxist theory to ozone pollution standards.
In an academic paper published in state-run journal Environment and Sustainable Development, the doctoral candidates from Beijing Normal University said Marxism could be used to set ozone standards, build monitoring stations and cut air pollution in China.
“Marxism tells us practice is the source of all knowledge,” the environmental science students wrote.
“In reducing ozone pollution, practice is the sole criterion for testing truth.
“Air pollution is a problem that concerns people’s lives … the Communist Party has always respected the role of people in history and society.”
