So as mentioned elsewhere within the Scienceblogosphere, the Ask a Scienceblogger Question of the week is:
“Will the ‘human’ race be around in 100 years?”
Short answer: yeah. Long answer: I’m not sure why there were scare quotes around “human” (are we going to mate with cyborgs or something?), but I think it will take quite a lot to totally wipe us out. We may not be as hardy as cockroaches, but we’re adaptive as hell, and even major events (volcanic eruptions, tsunamis, massive infectious disease outbreaks, etc.) haven’t done much to put a dent in our population. I do think, though, that our quality of living has a chance to take a real tumble. Already clean water is scarce for a sixth of the world’s population, and almost half lack adequate sanitation. We’re working on royally screwing up our environment, and increases in the amount of world travel mean that a virulent, easily-transmissible infectious disease could easily do some major damage (though not enough to put much more than a dent in our overall population, IMO). Will the next century bring improvements, or more destruction? Dunno, but I’ll bet $100 that humans will still be around to see it.
