How does the author use foreshadowing in The Coming Plague: Newly Emerging Diseases in a World Out of Balance?

Example of Foreshadowing:

"While the human race battles itself, fighting over ever more crowded turf and scarcer resources, the advantage moves to the microbes' court. They are our predators and they will be victorious if we, Homo Sapiens, do not learn how to live in a rational global village that affords the microbes few opportunities. It's either that, or we brace ourselves for the coming plague."
Chapter 17, pg. 620.
