Darwins theory of evolution can be explained like this; the environment actsas a selective agent, weeding out organisms less able to survive. Darwindescribed natural selection as a process in which organisms become betteradapted to their environment. The organisms that evolved with beneficialvariations are more likely to survive and reproduce, they pass on the favorablegenetic material. Over time, the genetic composition of the species may becomebetter able to escape being eaten or to capture prey. Do to such high demand forantibiotics around the world people have created their own antibiotic resistanceand became immune to antibodies. At least half of the human use of antibioticsin the United States is unnecessary or inappropriate. For example, a patientdemanding antibiotics for an illness that doesnt require them leads to a lotof unneeded drugs.
Either the antibiotics are not needed at all, or its thewrong dosage prescribed, or the wrong duration. More than 50 million pounds ofantibiotics are produced in the United States every year. Forty percent of thattotal is given to animals, mostly to promote growth rather than treat disease.Antibiotic use is also rampant in agriculture. Drugs are sprayed on to fruittrees to prevent bacterial infections. The bad thing is, is that these bugs aredeveloping a resistance to these drugs that once destroyed them.
We areexperiencing an alarming resurgence of common but no longer curable infectionsfrom bugs that developed resistance. This is by being too much involved withtaking antibiotics for every little sickness and all other things that wouldrequire antibiotics. Another thing that would pose as a problem is the way thatbacteria would evolve and adapt to our antibiotics. Darwins theory can berelated to antibiotic resistance in many ways. Through the years of usingantibiotics 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 theantibodies, the bacteria are adjusting to them faster. With all the antibioticsthat humans take in, their bodies are becoming immune to the effects. Which islike Darwins theory of natural selection; selecting out the organisms thatcant adapt or adjust to the environment around them.
