Process of bacteria growing immune to our medicine
Bacteria growing immune to the only thing that can stop them.
Animals eat food containing antibiotics.
These antibiotics spread in their bodies, and get into the meat, eggs, milk et cetera.
When we eat these products, we also consume the antibiotics. Consuming too much antibiotics causes our body to grow immune to it.
We are in fact, by eating, vaccinating bacteria against antibiotics.
These bacteria grow resistant and when they multiply, a large portion of them will be resistant as well.
When they multiply, and multiply again and again, eventually all the bacteria will be resistent.
Only so many types of antibiotics exist, and we'll run out sooner than we should.
