Basically the author argues that the way the agriculture industry sets up make endemics, pandemics and all of that would happen in increasing frequency and intensity but because capitalism sucks and the industry definitely would not let the appropriate authorities regulate them, we couldn't really fight this from not happening.

It's a good book but it has lots of scientific terms because the author is an expert in his field and he is not a journalist. He knows his things well so this is why it is a good book.
