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!
