Ever since the news of Zika causing microcephaly came up I have been wondering whether it&#x27;s a net benefit to humanity&#x2F;homeostasis if we were to exterminate Aedis Aegypti.  Can Zika spread among humans already?  It would seem like a huge risk to the future of humanity if this infectious disease interferes with reproduction.<p>What&#x27;s the worst-case scenario for letting Aedis Aegypti live?  Is it better than the worst-case scenario for exterminating the species?
