No doubt, snakes are the deadliest, venomous creatures but they are one of
the most beautiful creations of mother nature. It plays a great role in
Ecosystem. As like other wild creatures, their existence too is indeed
important to maintain nature's ecological balance. Snakes never attack
humans willingly else they get aggressive only when are hurt or disturbed
without warning. It's their natural wild instinct of self-defense that force any
venomous snake to strike. In fact, as much as we fear snakes, they too fear
humans and other bigger species.
