All we have to do is convince "alternative medicine" practitioners that rat tails from NZ cure baldness and make your dick grow. They'll be as extinct as the white rhino in less than a decade.
Nice theory, but when populations start to run low I guarantee these fuckers will just reintroduce them. We’re not talking about people with a lot of scruples here.
We won't eliminate them for even a second. The government doesn't fund its conservation department enough to even eradicate all the possums (which don't arrive in cargo) let alone the rats.
New Zealand is 268,021 square kilometres (103,500 miles), the rats are all through it including the parts that are inaccessible to humans.
It's nice that they are at least trying in some places, like in the article.
