Virus: What is the reason for COVID?

"If all the insects were to disappear from the earth, within 50 years all life on earth would end. If all human beings disappeared from the earth, within 50 years all forms of life would flourish."  -- Jonas Salk “At the highest levels of the medical cartel, vaccines are a top priority because they cause a weakening of the immune system. I know that may be hard to accept, but its true. The medical cartel, at the highest level, is not out to help people, it is out to harm them, to weaken them. To kill them. At one point in my career, I had a long conversation with a man who occupied a high government position in an African nation. He told me that he was well aware of this. He told me that WHO [World Health Organization] is a front for these depopulation interests” ― Jon Rappoport interview with ex-vaccine Researcher Pandemics...very scary. Why would nature create such things, when the majority of higher lifeforms are so beautiful, like humans and the rest of the animal kingdom. All other mammals thrive in the natural, but humans are sickened and diseased by what cause? Might there be a reason for a virus if it exists? I mean positive life-affirming reason for a virus, that has been overlooked or pushed to the side by greedy scientists, and a very powerful medical establishment and powerful corporations?...
