Well, let's face it. Once upon a time the killer bees had to get here on their own. As did the fire ants, and the chestnut blight, and the dutch elm beetles, and the starlings, and--and-and..... . . . Now, we can get those little critters here with great ease. Lets introduce snakes (poisonous ones at that) into Hawaii. Why should paradise be comfortable. Those folks should be afraid to step off the trail and go into the jungle too. Lets spread the misery all over. I bet our rattlesnakes would do well in asia. Or maybe ticks and red bugs and other nasty little biters and people eaters. I understand there is a super termite spreading throughout the southern US. I guess we'd better learn to make ceramic houses. Actually sounds pretty good. At least such a house would be fireproof except for what we put in it.
