Hi! Indeed yes. Man and large animals may carry as many or more microbes vis a vis their own body cells in their body - naturally, we comprise one of their natural habitats - reverse cannot be true.

Hi! Yes, all living beings are using the earth naturally - but man is increasingly becoming a destructive user of the earth's environment. In the name of civilization, man's race for supremacy, greed and ego is dangerously alienating environment day-by-day.

Thanks! Nice article with relevance even today. Man indeed understands the environmental problem, but does little.
