[1]_ left things alone, the threat posed by pests like rats would probably not have been
so serious. _[2]__thousands of years we have been moving species about for one reason
[31_ another but we have seldom achieved our objectives and have often _[41_more
harm than good. Rabbits were introduced into Australia, for example, __[5]_ the first place
as a source of food but they multiplied at __[6]__ a tremendous rate that they ___171_ to
be destroyed. Toads were introduced into the Pacific islands to provide food for lizards.
Lizards were introduced _[8]___ kill rats, but the poison in the toads' bodies killed the
Lizards instead. In Britain American grey squirrels were originally introduced just to look
pretty, and __[9]_ a result our native species, _[10]__ red squirrel, is now threatened
with extinction. It is quite obvious that voluntaristic human actions do not benefit nature.
People should always remember that everything is interconnected in wild nature. Each
voluntaristic human action can cause unpredictable consequences.
