My baby has an inner ear infection. Often times these ailments disappear on their own. Other times they get real bad. Thankfully we have Penicillin, which fixes it right up.

For now.

One day in 1928 — it was a Friday — the scotsman Alexander Fleming went about his daily business at St. Mary's Hospital in London. He was working in his laboratory when he discovered he'd forgotten to close up a petri dish of bacteria from the night before. What he noticed would change the world: a mould had grown in that petridish, and in a halo around that mould the bacteria had stopped growing. What Alexander Fleming had discovered would save tens of millions of lives in the century to come: this natural mould exuded a substance that had antibiotic properties. Not a decade later we had Penicillin, and on this Friday in 2014, Penicillin is helping cure my baby girl. Thank you, Alexander Fleming.

There's a problem, though. Penicillin is a wonderful drug, but bacteria — just like humans —  evolve and grow stronger. Put a drop of Penicillin in a petridish of bacteria and the bacteria will die. Probably. There's a tiny chance some of those bacteria will survive due to a random Penicillin-resistant mutation. Those lucky few survivers might reproduce and migrate. Repeat this process for a century and you're bound to have a couple of strains of bacteria to which even the strongest of Penicillins are useless.

We knew this would happen. Yet still to this day, Penicillin is used on a grand scale in meat-production of all things. When cattle have particularly bad living conditions, when too many cows are huddled up in too little space, they'll inflict little scratches on each other, wounds that might heal naturally on a green field of grass. But if your living quarters are also where you go to the toilet, no such luck. Hey, thought the meat industry, we can just pump the cattle full of Penicillin and no bacteria will grow in those wounds!

The way we treat our cattle is troublesome enough, but the inevitable consequences should be alarming. Those dirty farms and cattle transports are evolutionary crucibles for resistant bacteria. The strong bacteria will survive and require stronger Penicillins. It's an evolutionary arms race and we're losing. We always knew bacteria would evolve to be Penicillin-resistant eventually, but if we'd been smart about our Penicillin usage, we might've had enough time to research functional alternatives. As it stands, I'm worried about a future dad and his daughter battling an infection maybe just ten years from now. I hope she'll be alright, man.

So I guess here's another reason you should eat organic meat. Or no meat, that works too.
