I research about sources (both publications and authors) to see what credence I should lend them. The little I could find out about this book was a review at [0] that concludes with "I would not recommend this book to those beginning a study of Invasion Biology. It is a polemic presumably aimed at the practitioners of what the author holds is a pseudoscience, and perhaps also at policy‐makers."

Make of that what you will.

Thanks. I'm somewhat skeptical of the "invasive biology" scare too and would like to collect literature on the subject. Unfortunately I can't afford to buy every book on the subject ("buy used: $336.82", whats up with that?), but I did find a book review which gave a good summary I think:

He does seem to take an extreme position, but it is sometimes beneficial to take in an extreme counterpoint in order to find the reasonable "middle" ground.

I’d like to still have American manufacturing jobs
