Drug resistant bacteria has been around for ages. Antibiotics were naturally occurring, but now since the technological and expansion of mankind, antibiotics are now commonly used in all sorts of situations. This easily causes overuse and misuse of antibiotics creating antibiotic resistant bacteria (ARB). Certain main problem areas such as Waste Water Treatment Plants, factory farming, overusing general antibiotics (like penicillin), hospital hygiene or just hygiene in general, the difference between poor and rich medical care, use of antibiotics on crops, and the limited ways to kill bacteria enables bacteria to evolve which poses huge problems for future generations. Many issues influx the selective pressure of bacteria to evolve and resist the new and old drugs alike. Factory farming is a common perpetuator. In factory farming, animals are often fed loads of antibiotics for supposed "healthiness and growth." There are two types of antibiotics, one is growth promoting antibiotics and the other is a therapeutic antibiotic. Both are fed regularly within their food or administered around them. This causes the most of the bacteria festering in the pig or around the environment to die. Although, when not all the bacteria dies, new strains of bacteria appear that can protect itself from the antibiotics. Selective pressure means evolutionary change due to outside forces decreasing their chance of survival. This leads antibiotic resistant bacteria to be in the factory farmed foods we eat. The notion is simple, killing the bacteria with mass antibiotics on animals meant for human treatment not only raises chances in ARB, but also poses a problem should a type of bacteria become immune to our general accessible medication. Also, contracting any deadly bacteria can be as simple as just eating their infected meat and the resistant strain is given an opportunity to infect human beings. Thus the cycle begins to eradicate the bacteria via stronger and deadly drugs.
