This book is not available in print, so you either have to buy a used copy or ask a university for a scan. The author argues that the premise of “invasive species” is a racist Nazi pseudoscience and that there’s nothing wrong with introducing foreign species into an ecosystem. Apparently he has never heard of the Kākāpō: they were almost completely wiped out by the introduction of foreign species (cats, rats, stoats, pigs, deer, dogs, possums). They only exist on a few tiny islands now.
