Since the dawn of life species have come and gone and is seemingly the natural order of life. As such, some people feel there is little reason for humans to prevent this natural process from occurring, an opinion I disagree with unless it can be proven the demise of a species would be beneficial.

One of the main reasons why humans should protect animals is that we cannot be sure that if an animal species is going extinct, it is because of our actions, or because it is natural. Due to this uncertainty, any extinction may be attributed to human activity, even in part. It can also be argued, however, that since humans are a natural organism, we are also part of the natural order of things.  In other words, humans' effect on the Earth is a natural process from which the consequences could be considered as part of the natural evolutionary path of the planet.

This argument, though, is nihilistic for, as a higher species, we should do our utmost to protect all creatures within the animal kingdom.  As it is perhaps impossible for us to ever conclude with absolute certainty the specific cause of a species' vanishment, it is incumbent upon us to do our best to ensure a species' survival, for we are also unsure what the consequences are, not just on bio-diversity, but also on ourselves. Unless we can justify non-interference owing to a naturally-endangered creature being a threat to a benign species, or for that matter to ourselves, we should take action to prevent its disappearance. 

In conclusion, since it is impossible to confirm as to whether a species extinction is due to human behavior or to ‘the natural process’ of things, and since we should be able to cognize the importance of all creatures, I believe we should do our best to protect all animal species, particularly as we are also unsure of the ramifications on human life, unless it can be shown that a species' extinction is advantageous.
