Greetings friend@lupafilotaxia, undoubtedly all the inhabitants of the planet must be united, to solve together this problem of Covid, as it affects us all equally. However, there are governments and politicians in particular who only want to be protagonists by putting monetary interests first. Science has made very important efforts but they have been at times diminished by the lack of direct participation of these governments and politicians.
Thank you very much for your publication.
