One virus-induced pandemic was suffice to make air quality much better. It was probably nature's way of nudging humans to take air pollution seriously.
In the twentieth century, there could be no other topic that has become as trite as air pollution. In the last few decades, this word has garnered so much attention that it's almost run of the mill now. But does that mean we have become inured to this societal peril that chokes the lungs of the earth, blights its flora and fauna, depletes life-giving and life-sustaining resources, and threatens to annihilate all life sources? Anyone with a sound mind will have only one answer, we cannot ‘afford' to overlook the perils of air pollution.
It is estimated that 90% of the world's population is breathing polluted air; this means that 9 in every 10 people is inhaling unclean air or air that is laden with harmful chemicals like particulate matter, carbon monoxide, black carbon, nitrogen dioxide, sulfur dioxide, and the likes. The misty gossamer veils that loom over our cities in pre-dawn hours are the harbinger of a world that is consistently falling into an abyss. Sure, the low-income countries bear the brunt of air pollution the most and suffer the most; it is only a matter of time before this poisonous air permeates globally and engulfs all of mankind. If world nations don't vow and act upon their vow to reduce industrial emissions, it will be too late for redemption.
Human activities, from burning fossil fuels in houses to crop burning in farms, motors belching vicious fumes, and industrial gases billowing up in ribbons are all contributing generously to this ubiquitous menace. It has been exacting a heavy toll on public health as well.
Air pollution can be and should be eliminated at any rate but a quick-fix is not plausible. But it can be significantly mitigated by replacing fossil fuels with solar, wind, and geothermal energies which are renewable. Pegging down consumption of energy may seem like an unachievable dream but judicious usage can play a vital role in reducing the depletion of non-renewable energy resources. Preventing deforestation and planting more trees can go a long way towards achieving a cleaner atmosphere as plants can sponge the malicious gases that cling to air as smog and smoke etc.
