The third-deadliest species for humans are snakes, which are responsible for 50,000 deaths every year. Nearly ten times as many people meet their deaths at the hands of other people, totaling 475,000 annual fatalities. Mosquitoes are the world's number one killer, according to the 58-year-old philanthropist.
The most common cause of death was humans being infected by a dog with rabies. However, the National Canine Research Council reported that fatalities from dog maulings are extremely rare. In 2010, only 33 cases were reported of people being killed by a dog mauling. Snakes were ranked third for causing 50,000 human deaths a year. Of the roughly 3,000 snake species that exist in the world, about 600 are venomous, according to a study published in the PLOS Journal of Medicine. Humans were ranked as the second highest killer of the human race, averaging around 475,000 deaths caused by suicides and homicides.
