Abstract

The world leads off an exceptional 2021 year, burdened with unprecedented uncertainties and challenges. Since the first days of 2020 and the unmatched pandemic has not recovered or retreated. The burden of the health sector and the unparalleled number of deaths around the World have been the biggest challenges that sparked many protests and spread fears in various societies, especially in the absence of any operative treatment and the long wait for an effective vaccine that provides the “social” adaptive immunity and helps restoring the institutional abilities to approach the financial crises and economic collapse resulting from the contagious spread and the pecuniary damages resulting from the total lockdown that has been imposed to establish relative social distancing as a lone solution to limit the spread of the virus. As recent events have shown, especially with the appearance of mutated strains that pandemics do not respect geographical boundaries, therefore a globally focused effort is direly needed to combat the viral drift representing the current but the unique threats to humanity amid the complexities of climate change and globalisation.
