I really appreciate your bringing that question up. It's so important.
We often vilify micro-organisms, but they're an integral part of our ecosystem. Birds live in the trees, fish live in water and bacteria live all over the place, including on our bodies; and they do good things. The issue, of course, is that once in a while they get into the wrong place and cause disease.
The key word here is “stewardship”. We don't give antibiotics out like Halloween candy. We use them appropriately when someone is ill. When we start using them inappropriately, with misuse or overuse, we run into problems.
There are no issues with clinicians or doctors prescribing antibiotics for routine medical issues. That's not going to impact us if we use them appropriately. Where we run into problems is in the animal health sector, where 70% of the global consumption of antibiotics.... That is a key driver. If we ignore that, we're missing the point.
It's an issue when a physician accidentally gives an antibiotic for a viral respiratory tract infection. We need to work on that and do better, but we cannot ignore the other 70%.
Again, if we use the antibiotics appropriately, we'll be okay, and we'll preserve this very vital resource.
