Final answer:
The overuse of antibiotics can lead to antibiotic resistance, disrupt the natural balance of bacteria in the body, and contribute to the development of new strains of bacteria.
Step-by-step explanation:
The overuse of antibiotics is a bad thing because it can lead to antibiotic resistance. When bacteria are exposed to antibiotics repeatedly, they can develop ways to survive and resist the effects of these drugs. This means that the antibiotics may no longer be effective in killing the bacteria, leading to the spread of drug-resistant bacteria.
Furthermore, using antibiotics when they are not needed can disrupt the natural balance of bacteria in the body. Antibiotics do not only kill harmful bacteria, but also the good bacteria that help keep our bodies healthy. This can result in side effects like diarrhea and yeast infections, in addition to allowing harmful bacteria to flourish.
Lastly, the overuse of antibiotics can contribute to the development of new strains of bacteria. As bacteria are exposed to antibiotics, some may mutate and develop resistance. These resistant strains can then pass on their resistance genes to other bacteria, making them even harder to treat.
