i don't agree with his theory because humans make lousy bacteria. we have the ability to live in harmony with the earth and not destroy it

bacteria don't destroy the earth... Bacteria were the only form of life on earth for 2 billion years, they did a pretty good job with it.

bacteria cause an illness which destroys the host (a human for instance), while humans are destroying their host (the earth)

The human body contains a large number of bacteria, most of them performing tasks that are useful or even essential to human survival. Those that are expected to be present, and that under normal circumstances do not cause disease, are termed normal flora.

It is estimated that 500 to 1000 different species of bacteria live in the human body (Sears, 2005). Bacterial cells are much smaller than human cells, and there are about ten times as many bacteria as human cells in the body (1 quadrillion (1015) versus 100 trillion (1014); Sears, 2005). Though normal flora are found on all surfaces exposed to the environment (on the skin and eyes, in the mouth, nose, small intestine, and colon), the vast majority of bacteria live in the large intestine.

Many of the bacteria in the digestive tract, collectively referred to as gut flora, are able to break down certain nutrients such as carbohydrates that humans otherwise could not digest. The majority of these commensal bacteria are anaerobes, meaning they survive in an environment with no oxygen.
