Is Mankind a Pathogen?

I just ran across something in a book on composting human bodily waste:

"...There is a disturbing theory about the human species that
has begun to take on an alarming level of reality. It seems
that the behavior of the human race is displaying uncanny
parallels to the behavior of pathogenic, or disease-causing,
organisms.
When viewed at the next quantum level of perspective, from
which the Earth is seen as an organism and humans are seen as
microorganisms, the human species looks like a menace to the planet.
In fact, the human race is looking a lot like a disease — comprised
of organisms excessively multiplying, mindlessly consuming, and
generating waste with little regard for the health and well-being of its
host — planet Earth..."

Or as the agent says in the Matrix: "Mankind is a virus...we are the cure!"
