The
IUCN's
Invasive Species Specialist Group has drawn up a list of the
100 Worst Invasive Species which highlights the
unintended consequences of humans
deliberately + accidentally moving organisms from
where they evolved to new places where they can be
highly disruptive + difficult to control.
In addition to the (often overlooked, but frequently
ecologically devastating)
domestic cat you might have heard of
crazy ants,
cane toads +
brown tree snakes...
On reading up on the
brown tree snake (BEWARE! Extreme snake close-up!) I was amazed to learn that in
Guam these snakes have caused numerous
island-wide powercuts - in addition to munching their way through native animals galore!
