Why does this make me nervous?

probably visions of Cane Toads in Oz or the Mongoose in Jamaica or Foxes
in Oz.......
I do hope the research is done properly.

While cleaning my teeth this morning I pondered this question for the two
minutes my sonic brush allows me, for no good reason I could think of
except that I was looking out at the back garden.

I reckon that there are more 'safe' biological controls than there are
undesirable ones.

Over all of history I'm not so sure, although that's probably down to
stupidity and/or desperation coupled with a lack of understanding/research.
I understood most of the "safe" ones use native insects/fungi/bacteria not
imported ones.
