Invasive!!

Who causes invasive species?

"On a dark night last week a group of animal rights activists in Donegal made their own special contribution to the International Year of Biodiversity. They cut their way into a fur farm and released 5,000 mink. This, within their circles, was considered a clever thing to do."

"Had these people tipped a tanker load of bleach into the headwaters of the river Finn, they would have done less damage. The effects would be horrible for a while, but the ecosystem could then begin to recover. The mink, by contrast, will remain at large for years, perhaps millennia. Like many introduced species, American mink can slash their way through the ecosystem, as they have no native predators, and their prey species haven't evolved to avoid them. Is there anything the animal lovers in Donegal could have done that would have harmed more animals?"

"The mink, the walking catfish, the cane toad, the mutant house mouse, these are potent symbols of humanity's strangely lopsided power. We can sow chaos with a keystroke in an investment bank, one signal to a Predator drone, a seed dislodged from the sole of a boot, a fish tank emptied into a canal."

"Our challenge this century is to meet our capacity for harm with an equal power for good."
