The Tiger dosent even know that its endangered and there are only a few left , But we humans who are intelligent and known to be much superior cant understand the simple fact of extinction. Every species which is going towards extiction is finally going trigger mass extiction which will be the final swipe and no living being will exist. Are we ready to face the wrath of Mother EARTH ! No weapons ,no technology , nothing will save us from this !! Or we can say that God will pull civilisation down for overspeeding !!
