Abstract
Since 1992, the Red List of the International Union for the Conservation of Nature enlisted that three hundred and forty-nine new species had been discovered. Of this huge number, about 51% of them were expected to reach extinction. It was only 5% of all the recognized species that had a stable rise or increase in population growth. Since the evolution of life on planet Earth, various species have disappeared due to natural or, more recently one might coin it as human causes. The questions that would now plague one's mind would focus around the causes for extinction, whether the human race is capable of playing a predominant role in preserving these species. If these queries are summarized, and if asked to condense these questions in a nutshell, one would be keen to understand the circumstances for these species and its unique disappearance and further, can the human race strive to prevent and protect these mass extinctions. First of all, a simple question on the definition of extinction is answered as - the dying or the fading out of a species. It is a Herculean task to participate in the determination of its frequency of its occurrence. However, it is generally considered to be at the death of the last individual of the species. It is estimated that 99,9% of all species that have ever lived have now reached extinction. So, let's discuss, if extinction is a natural phenomenon?
