Here’s an interesting trivia question: what animal kills more human beings every year than any other? The shark? The lion? Rhino?
The answer is the mosquito, and the statistics are not even close. Over 400,000 people were killed last year by mosquito-borne malaria. Mosquitos carry four different encephalitis viruses, plus the West Nile virus—and most recently, the Zika outbreak that is threatening attendees at the Rio Olympics.
