A vaccine against Covid-19 is desired, it is necessary, without a doubt, but due to the impressive impact that it has had on the economy, health system, and society in general all the attention is focused in that sense, however, it is good to note that the emission of toxic gases has diminished considerably due to this forced stop, and this has brought a great benefit for the world in relation to that complex adverse effect of Industrialization that has been called Global Warming.

Increase in vegetation, decrease in global temperature, record low figures for CO₂ levels in the environment are just some of the data that tell us about the benefit that the environment has had in the face of this reality.

There is a great detail when this type of crisis situation occurs, which fortunately are not usual, and it is that some activities that are promoters or direct cause of many disasters that occur in the world are paralyzed, and are put in evidence (as in this case) with other situations that begin to improve as if by magic.

And NO, it is not magic, of course, nothing to do with that is simply a clear demonstration that a possibility to improve this situation exists, that it is only necessary that some developed countries (mainly) become aware of it and manage to decrease their levels of pollution, but I consider that it is not necessary that we have a Pandemic and that it is seen as a vaccine for global warming .
