The discussion highlights the staggering number of viruses that exist beyond the pathogenic ones we often hear about. With a mind-boggling estimate that there are 100 billion times more viruses in the oceans than grains of sand on all the world's beaches, the scale of viral diversity is almost incomprehensible. Viruses, which are not considered living organisms, rely on invading cells to replicate, turning them into production factories for more viruses.
