Climate Since Covid

Only time will tell what the final effects of the COVID shutdowns are on the environment. During the height of the lockdown, air quality improved almost immediately. NO2 and CO2 (from fossil fuels) both decreased. This effect was noticed most heavily in major cities, though arguably the whole world benefitted. Fine particulate matter, PM2.5, similarly dropped.

Air Purifying Plants

Plants are natural air purifiers. We put out a heck of a lot of carbon, and all plants will help reduce that to some degree. The only issue is that carbon isn't the only thing we're putting into the atmosphere. Our atmosphere indoors, where we're spending so much time, is incredibly important. We put out a few other notable bad chemicals in the course of daily living - ammonia, benzene, formaldehyde, trichloroethylene, and xylene. Check here for some plants that can clean your air!
