Nature is made of atoms.

Same thing is valid for viruses. And for people.

Both viruses and people are atoms put together according to specific sets of rules.
Further more, the same sets of specific rules determine how each of them interact with the places where each of them happen to live.

I need to make a pause here.
And mention the fact that life alters, profoundly – if given enough time, the space where it ‘unfolds’.
For instance, the blue-green algae have transformed the Earth atmosphere into what it is today.

We balk at it today but blue-algae, also known as Cyanobacteria, is responsible for the Earth atmosphere having so much free oxygen.

Same thing is valid for viruses. And for people.

Viruses which kill too much of what they get in contact with do not survive for long.
They either peter out, like Ebola usually does, or have been wiped out. Like small pox was. And polio is close to be.

People who destroy too much around them… soon find out they no longer have a viable home.

And this is valid both for individuals and for the entire species.

Nature, on the other hand, doesn’t care.
It simply goes on.
