Non-Native Species

The introduction of non-native “exotic” species is now seen as a major threat to biodiversity. In 1825, a particularly vigorous female clone of itadori (called Japanese knotweed) was introduced  into Holland and later _______ throughout Europe by the plant collector and nurseryman (园丁), Von Seybold. British gardeners loved it and by 1886 it was even found growing on cinder tips in South Wales. By the turn of the century, the plant had _______ many other sites, and gardeners were advised against planting it in shrubberies. By 1994, it was almost everywhere-railways, riversides, hedgerows, cemeteries - swamping a wide range of habitats and displacing _______ species. Botanists’ fears that the plant is still spreading and may yet colonize other new habitats have generated recent attempts to eradicate it by mechanical and chemical methods, all _______ as yet.

The evidence stacked against Japanese knotweed is damning (足以定罪的). But there is a deep

_______ that behind the desire to correct human ecological cook-ups (策划)- often manifested as a passion to save endangered species and vulnerable ecosystems - is a thinly disguised xenophobia (仇外心理); that we are simply seeing yet another form of ecological imperialism (帝国主义) which defines what is “natural” based on human _______

But whatever our reaction to “problem” or alien species is, it must _______ moral decisions. And who should make such decisions and to what _______ they are accountable must also be up for review. The conclusions of scientists and other sections of society may differ _______ about what to do about the introduced animals and plants. ________ the scheme to control rabbits in Australia by deliberately spreading the disease myxomatosis was a success in that huge numbers of rabbits were wiped out for the greater good - the “health” of Australian ecosystems. But would inflicting (使遭受) such a ________ slow painful death on sentient (有感知能力的) creatures win popular support if it were proposed today?

Scientists of ________ are by their very nature concerned with the organization of species into systems and not necessarily with the interests and well-being of ________, particularly those that are seen as a threat to the maintenance of those systems. Yet there is a growing feeling for the democratization of decisions concerning nonhuman life. The ________ towards environmental values must surely involve a movement away from imperialism and a search for a relationship with nature as it truly is, rather than as we would design it. Then, when our ________ has/have long disappeared, we may yet come to honor the humble itadori.
