Antibiotics have saved countless lives in the last 80 years, but they’re not as effective as they once were. We use too many of them, and so bacteria are developing resistance more quickly than we can come up with new drugs. Why are we using too many of them? Because they are too cheap. We even use antibiotics to make cattle grow faster… The price of the new antibiotics should be much higher to discourage their use in farms and protect human health.
