"Climate change may be a greater threat than terrorism, but a flu pandemic is a more immediate threat than either."

Let's have some more numbers from Dr Osterholm, just to encourage you. He writes: "It is sobering to realize that in 1968, when the most recent influenza pandemic occurred, the virus emerged in a China that had a human population of 790 million, a pig population of 5.2 million, and a poultry population of 12.3 million; today, these populations number 1.3 billion, 508 million, and 13 billion, respectively. Similar changes have occurred in the human and animal populations of other Asian countries, creating an incredible mixing vessel for viruses. Given this reality, as well as the exponential growth in foreign travel during the past 50 years, we must accept that a pandemic is coming - although whether it will be caused by H5N1 or by another novel strain remains to be seen."
