Well, what would happen if Australian bees died out? Well, the honey from Australian bees is of excellent quality, much better than the stuff the Asian bees produce. In fact, Australia exports native Queen bees to a large number of countries because of this. When the European Honey Bee was first discovered out in the bush, we found they made really unpleasant honey and they were also too big to pollinate many of our native flowers here in Australia. That must have had a devastating effect on the natural flora. Did you lose any species? No, we managed to get them under control before that happened but if Asian bees got in there could be other consequences. We could lose a lot of money because you might not be aware, but it's estimated that native bees' pollination of flower and vegetable crops is worth 1.2 billion dollars a year. So in a way they're the farmers' friend. Oh, and another thing is, if you're stung by an Asian Honey Bee, it can produce an allergic reaction in some people, so they're much more dangerous than native bees.
