Before the widespread use of antibiotics, there were very low levels of antibacterial resistance. As antibiotic use has grown, so has the number of antibiotic resistant bacteria. WHY do you think this has occurred?

This is because antibiotic resistance can be caused by bacteria getting the ability to be unaffected by the antibiotics Also, people not taking their medication for the entire duration exposes the bacteria to the antibiotic and makes it stronger. Also, when people overuse antibiotics and mutations occur, the bacteria becomes antibiotic resistant.
