Where's the reciprocity?
Mosquitos are one of natures grandest design failures. Instead of being humble members of the ecosystem, thankful of the blood they suck from creatures thousands of times their size, they opt for the ways of spite. Imagine how much safer the mosquito world would be if only these insects could be redesigned to avoid the unpleasanties associated with a bite. We probably mostly wouldn't care for their existance.
Unlike now, where we quickly move for a kill given the chance. It's just not smart. I vote for genetically modified mosquitos that will allow man and insect to live happily ever after.
I am of course under no small influence of the ten or more bites I've suffered the last couple of days, so don't sue me if these mutant mosquitos move for world domination or what have you.
