Snakes - Snakes And Humans

people york body temperature

Snakes have fascinated and frightened people for millennia. Some cultures worship snakes, seeing them as creators and protectors, while others fear snakes as devils and symbols of death.

While some people keep snakes as interesting pets, most people harbor an irrational fear of these reptiles. Unfortunately, this attitude leads to the deaths of many harmless snakes. Certainly, a few deadly species of snakes can kill a human, and no snake should be handled unless positively identified as harmless. However, the estimated risk of a person suffering a bite from a venomous snake in the United States is 20 times less than being struck by lightning—this is an extremely small risk. Snakes are useful predators, helping to reduce populations of pest rats and mice. A well-educated, healthy respect for snakes is a benefit to both snakes and humans.
