We spend 85% of our time indoors, and air conditioning can provide relief when and where we need it. Nevertheless, regulatory agencies continue to press for tighter outdoor emission controls. Their mantra is that lives can be shortened by long-term (years) exposure, no matter how trivial. This is the linear, no-threshold hypothesis currently promulgated by EPA.
indoor air quality
Since the beginning of the modern environmental movement in the 1970s, air pollution has been defined as the debasement of the outdoor ambient air. That movement has been a resounding success. Accompanying these benefits has been the recognition that the indoor environment is now relatively more important. The EPA has responded with citizen advisory programs but little information on indoor risk or remediations.
The climate is changing while concerns about air pollution linger on.
Air pollution and COVID-19 share at least one attribute: their concentrations and your exposure differ inside and outside. Are we better off, indoors or outdoors?
Two great articles on what we really know about COVID-19 and a graphic explanation of vaccines, how government regulations are working against us, and having spent the last two months indoors, perhaps we should become a bit more serious about our indoor air quality.
