Article(#3): Thoughts for a Countdown

The Earth's Moon

The article started out with the introduction of astronauts returning to Earth from the Earth's Moon.  The author mentions the "ceremonies" they conduct as they land on Earth. Such "ceremonies include meeting the president, staying in sealed boxes, and other "antiseptic ceremonies".  The author shows that astronauts may have carried back organisms from space, and hence they must conduct all those careful "ceremonies".  By generalizing, the author may have meant that in this century, most people would be in fear for the findings of new organisms and the diseases they may carry.  People tend to have fear towards microbes and they are often  forgetful of the symbiotic and beneficial abilities of many microbes.  The technology we have now are not yet capable in studying microbes even on Earth; there is a chance that many more are not yet studied.  This is the case, because most microbes cannot be cultivated in our present labs or have not yet been discovered.  Therefore, certain bacteria and fungi serves as models to help scientist study the nature of microbes and other organisms.  

Some bacteria live in cockroaches; they are in the mycetocytes of cockroaches and termites and are later transmitted to future generations.  Although it is not for certain, bacteria are beneficial to some insects.  Even eukaryotes 's origins may  have been from prokaryotic cells.  In sea life, for example, crabs and damsel fish recognize others with certain anemones. Some organisms and their hosts even make hybrids when their cells make its way to their hosts.  Therefore, the fear of new organisms may be unnecessary, since organism may form hybrids or work together on Earth.
