A pandemic carries manifold impacts on civilization, and obviously, the human health system faces the initial surge. The unfortunate spillover of the Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), making a cross-species transmission to jump from its initial host species and spreading within the human population, has emerged as an unprecedented health crisis in the recorded history of civilization that breaks all statistics of fatalities. The malicious virus has reached all the continents and discharged its hostile behavior against the human immune system against which the practitioners of medical sciences and the associated human resources are combating. The vaccine of the virus is at the human trial phase when this book is being written.

The world witnessed the complete disruption of the world’s most reliable health infrastructures of the European nations and then the USA triggered by the surge of fatalities and infection. The disease epicenter has been transferred to Latin America, especially Brazil, and then South-Asia, especially India. The last phases of the disease are significant because the clusters of the disease have started concentrating over the country groups that accommodate comparatively less public healthcare points and life-support infrastructures in comparison to the population they hold. It not only bottlenecked the public health system, instead, it posed many more challenges on the border horizons of society, economy, education, and policymaking. This volume brings this pandemic trajectory within its folds. The long period of lockdown all over the globe has resulted in environmental reinvigoration and diminishing of the pollution level. Populous cities are becoming “greener” and “cleaner” than how they were before the lockdown. However, the debate emerges what the world would think ahead—the boon for the natural environment or the bane for the economy as the form of income insecurity, unemployment, and hunger. The question arises—whether the “green recovery” will be long-standing? Whether the indiscriminate use of alcohol-based
