“The 21 million inhabitants of China’s capital appear to be engaged in a city-wide rehearsal for life on an inhospitable planet. Only it’s not a rehearsal: the poisonous atmosphere is already here.”
Of course, all this was spelled out in the 2012 children’s movie “The Lorax.” But very few people watched that movie or understood what it meant.
Newsflash for humanity, we can’t possibly clean all the air that we pollute. Invariably that pollution rises into the atmosphere and comes down somewhere else, in other toxic forms.
