    Jan 20, 2021The poor and most vulnerable will suffer most from both the health impacts and the economic crisis. Cleaner air for a few months may be a tiny silver lining to COVID-19’s dark clouds, but will do little in the long run to solve the problem of outdoor air pollution that kills more than four million people every year. For that we need to kick our habit of burning coal, oil and gas.
