Why are antibiotic resistant bacteria considered a problem

Bacteria that have obtained the ability to resist the effects of antibiotics. As the diseases caused by these bacteria are hard to treat.  

Explanation:

Darwin proposed that evolution is caused by natural selection.  

During the industrial revolution caused tons of soot has been deposited in the countryside around industrial areas. The soot discoloured and generally darkened the surfaces of trees and rocks.  

In 1848, a dark-coloured moth was first recorded. Today, in some areas, 90% or more of the-peppered moths are dark in colour. More than 70 species of moth in England have undergone a change from light to dark. Similar observations have been made in other industrial nations, including the United States.

Overusing and misusing of antibiotics causes antibiotic resistance. The ability of bacteria to resist the effects of an antibiotic is known as antibiotic resistance.  

It occurs because of overuse and misuse of antibiotics over a long period of time. It also occurs if we do not use it as prescribed.  

Antibiotics should not be taken every time we feel uncomfortable. We should not save it for next time and should not share it with others. If we overdose ourselves with it we may have serious side effects which can make us feel worse.
