Assignment: Take one of the three articles given to you. Do you agree or disagree with the author? Use the text to support your argument.
In "Thoughts For A Countdown" by Lewis Thomas he first starts off by explaining how astronauts live in a state of isolation soon after they come back from their moon expeditions.. They must go through a "long antiseptic ceremony... then they are allowed out into the sun." Humans have an "obsession with disease and death" therefore astronauts must be inspected for viruses or any other contagious disease that will affect us in any way. I agree with his statement " Every creature is, in some sense, connected to and dependent on the rest." It is true many organisms on this earth have symbiotic relationships and without them they would not survive. For example, the bacteria that lives in the tissues of cockroaches appear as required organs for its host. The cockroach could not live without this bacteria. As for the relationship between the moon and the earth, the astronauts most likely have not caught a disease because " it takes long intimacy, familiar inter-living, before one kind of creature can cause illness in another." It is important to know the types of relationships between organisms because they help in the findings of something beneficial for all types of organisms not just for a certain specie.
