At the United Nations last month there was a major meeting at the sidelines of the General Assembly about an issue called anti-microbial resistance. This meeting did not make much news outside the UN bubble, but it was arguably the single most meaningful thing to happen at the United Nations in months.    Anti-microbial resistance is one of the worst global health crises in the world that gets the least amount of attention. The short story is that the antibiotics we use to treat common infections are becoming less and less effective. There are many reasons for this, including the overuse of antibiotics in livestock and the over-prescription of these drugs for humans. The implications of ever-increasing anti-biotic resistance is exceedingly profound for both the health and wealth of our entire planet. The foundation of modern medicine is in peril.    On the line with me to discuss the problem of antibiotic resistance, its origins, and what the international community is doing to confront it is Elizabeth Tayler. She is with the World Health Organization and is one of the few people on the planet working day in and out to reverse this trend. Tayler does an excellent job of describing the root causes of anti-microbial resistance, its implications for modern medicine and what the global plan is to confront it.
