Mankind is just going to keep messing in areas he has no business messing in. Why not use shotguns?!
Because there were millions of these rabbits, even in the cities. Shotguns would not be very effective as they were in so many areas. I think we have been using these viruses since 1995 and it has been very effective. Ten years ago, the bunnies were tearing up my yard and flowers. I have not seen a bunnie now for about 3 years, although there are a few around. We still have foxes that were also introduced and they are also great pests killing the natural fauna.
