Cleaner air during pandemic lockdowns shows what s possible, say researchers Roughly one year ago, city streets across Canada were deserted. There were virtually no cars, no trucks and few buses as the country went into lockdown mode. Shops and buildings were closed. Most people stopped commuting. And it was the same across most of the world. While millions of lives have been lost due to COVID-19, and people have suffered economic consequences, these short-term global shutdowns have had a marked effect on the environment.  The amount of pollutants that were pumped into the atmosphere dropped noticeably including in southern Ontario, where a recent study documented a 20 per cent drop of some pollutants compared to recent years.
