The selfishness of mankind has led the world to such a situation, as we see today in all countries.
In just 3 months, the number of infected increased to 1 million, and the number of deaths - up to 100,000. The only way to prevent all this is to separate again from each other bringing human communication to zero. But let's hope that as a result of vaccination, humanity will return to normal life, and in the end, the only thing that humanity can do is to unite. In particular, to unite the world healthcare system will help prevent similar situations in the future organized and faster.
