This is an excerpt from an article that was written in 1956. Some scientists venture the guess that there are at least 3,000,000 different kinds of animals living on earth. And if the tiny microscopic kinds are to be taken into account, there is no telling how many millions actually exist. Parasitic animals are very abundant, and there is practically no animal on earth that is not infested with some kind of parasite, internal or external, and that includes man. Some one once said, "Great fleas have little fleas upon their back to bite 'em, and little fleas have lesser fleas, and so on ad infinitum." So man, though he thinks he is the big shot of creation, is actually a tiny part of life on the earth. In fact, there are billions of times more animal life on earth than there are human beings. We need to know that other creatures dominate the earth in many ways, and that we are at their mercy in many cases. http://tinyurl.com/297f7v
