h2g2 The Hitchhiker's Guide to the Galaxy: Earth Edition

Well, you forgot to mention the air-conditioned domes that have upper coverings that retract to increase the aforemetioned hemoglobin-consuming insects.

Ah yes, that's right. But of course, the aforementioned retractable-roof mosquito trap is not quite finished. So...yep.

Really, when you think about it, Houston was pretty much built on a swamp. As was much of the Gulf Coast. Yep, when we came here, all there was was a swamp. And everyone said "Hey, you idiot, you can't build a city there. You don't got enough air conditioning to survive." and we replied "What the hell is air conditioning?!" and built the city anyway, just to show 'em. Actually, all of our oxen died of malaria, so we couldn't go much further. Damn mosquitos.

That would explain why Houston floods once or twice every year, and you can swim through the streets.

I must beg to differ on one point, however, because your mosquitos ain't squat. To make them really ferocious, you have to freeze the larvae for about six months somewhere up North in, oh, maybe, let's say, Michigan. Down there, Mosquitos love the heat & humidity. Here the mosquitos are *born* pissed off.
