Agreed @Arkiven4.  Many of the big scientists and public health specialists have warned there are more viruses to come.  

For me the bottom line is a world that has too many people relative to the resources available, and there are too many over populated places.  This is probably going to sound a bit "out there", but if one checks the countries with the largest number of corona virus cases, they are also the countries with areas  of mass population (hot spots) where very many people are living almost on top of one another and in one another's space.  Take the US for example, and most of the cases are concentrated in overpopulated places.  Ditto Italy, Brasilia, India and more.  Corona virus thrives in areas that are lacking in ventilation and where large numbers of people are congregating together for longer periods of time.

I'm looking forward to the vaccines, but wonder what the long term consequences are going to be.  To create a vaccine of a virus that even now scientists don't have a full picture and comprehension of the virus, how could they full understand the long term effect of the vaccine?
