Over the past few decades, humanity has spent more time dancing around improving air quality and taking less action. Indeed, humans need to alter how they live and consume the planet's finite resources. Globally, most economies are fossil fuel-based, and their emissions contribute to the degradation of outdoor air quality. Without strict government emissions regulations and incentive programs to raise the bar of outdoor and indoor air quality, the rising tide of air pollution will have early and well-pronounced effects on public health globally as it has already impacted climate change. \u003c/p>\u003ch2 >\u003cstrong >Preaching the Air Quality Promise\u003c/strong>\u003c/h2>\u003cp >Many air quality and filtration experts believed the pandemic would promise better air quality. However, engineers cannot go far with air quality if existing political institutions move slowly, even if they are well-intentioned. Although many global voices demand international cooperation to make air quality a global priority, logistics, actions, and outcomes have not lived up to the expectations and the nature of change the planet strives for. The business models of capitalism that drive global economies typically reward those leaders for maximizing the bottom line and short-term profits, not addressing major environmental, social, and governance (ESG) issues. On every occasion where leaders intend and insist on making a difference on the pressing issues facing humanity, the argument emerges that success on a global scale takes time. Unfortunately, the pandemic swallowed any time that remained.\u003c/p>\u003ch2 >\u003cstrong >Smart Is Clean and Green\u003c/strong>\u003c/h2>\u003cp >Although the environmental challenges before us are grand, the current situation represents a historic calling to sink or swim by bending the arc of waste in resources, energy, materials, and even human potential toward a sustainable future. COVID-19 is not precisely the Spanish flu, and this isn't 1918. Humanity is now far more equipped to make a difference faster than ever. However, it is not enough to speak the sustainability language; humanity needs to be on the same action page. Let humanity gird for a marathon, not a sprint, as existence aims to solve outdoor and indoor air challenges. Humans' actions have wounded the planet for decades rather than contributing to its bio-generation. Settling for imperfect compromises and experiences are expected, but efforts to advance the cause must eventually converge as time is, undoubtedly, of the essence. What would our world be like if smart cities had built environments filtered professionally through a responsive HVAC system that acted immediately to any changes in IAQ?
