FREE ESSAY ON ANTIBIOTIC RESISTANCE

ANTIBIOTIC RESISTANCE

Darwin's theory of evolution can be explained like this; the environment acts as a
selective agent, weeding out organisms less able to survive. Darwin described natural
selection as a process in which organisms become better adapted to their environment. The
organisms that evolved with beneficial variations are more likely to survive and
reproduce, they pass on the favorable genetic material. Over time, the genetic
composition of the species may become better able to escape being eaten or to capture
prey.
Do to such high demand for antibiotics around the world people have created their own
antibiotic resistance and became immune to antibodies. At least half of the human use of
antibiotics in the United States is unnecessary or inappropriate. For example, a patient
demanding antibiotics for an illness that doesn't require them leads to a lot of unneeded
drugs. Either the antibiotics are not needed at all, or it's the wrong dosage prescribed,
or the wrong duration.
More than 50 million pounds of antibiotics are produced in the United States every year.
Forty percent of that total is given to animals, mostly to promote growth rather than
treat disease. Antibiotic use is also rampant in agriculture. Drugs are sprayed on to
fruit trees to prevent bacterial infections. The bad thing is, is that these bugs are
developing a resistance to these drugs that once destroyed them. We are experiencing an
alarming resurgence of common but no longer curable infections from bugs that developed
resistance. This is by being too much involved with taking antibiotics for every little
sickness and all other things that would require antibiotics. Another thing that would
pose as a problem is the way that bacteria would evolve and adapt to our antibiotics.
Darwin's theory can be related to antibiotic resistance in many ways. Through the years
of using antibiotics against bacteria, we have seen that they usually get the job done.
But as time progresses, so do the bacteria. As fast as we are producing the antibodies,
the bacteria are adjusting to them faster. With all the antibiotics that humans take in,
their bodies are becoming immune to the effects. Which is like Darwin's theory of natural
selection; selecting out the organisms that cant adapt or adjust to the environment
around them.
