How are snakes helpful in the world?

Answer:
Snakes can provide good entertainment and are useful in the study of various actions regarding reptiles. In many areas, they can also help keep rodent populations in check. Their venoms are often involved in the study of complex proteins and organic compounds (since they are excellent examples of both), and this in turn is used in the study of various medicines.
