We've put huge resources into predicting tsunamis, hurricanes, and earthquakes. HIV/AIDS is like an earthquake that's lasted 30 years and touched every country on the planet. We have such incredible capacity to think about the future, it's time we used it to predict biological threats. Otherwise we'll be blindsided again and again.

We may have charted all the continents on the planet, and we may have discovered all the mammals, but that doesn't mean that there's nothing left to explore on Earth.

Swine flu is not an anomaly. We know that swine flu - like the vast majority of new outbreaks - comes from animals. We should be monitoring those animals and the humans that come into contact with them, so we can catch these viruses early, before they infect major cities and spread throughout the world.

Seasonal flu is now a pandemic that lasts for years and years because you've got so many people that it's jumping back between northern and southern hemispheres and moving itself around the world. By the time it gets back to where it started, it's changed sufficiently so that people are no longer immune.
