The evolutionary record is piled high with the bones of extinct species, extinctions caused by changes in the environment or by other species. We are not unique, we are just one of many millions of species to find a way to rapidly outcompete others but the difference is that we often choose not to. So far we can’t even hold a candle to the humble cyanobacteria in terms of wanton destruction of their environment and all life on the planet when they evolved the ability to photosynthesize. Similar though less dramatic events have likely occurred with each major evolutionary adaptation that allows a species to exploit something not available to others. For us it’s intelligence but for others it was eyes, fins, teeth, legs, claws, etc. all leaving a path of destruction and allowing the possessors of such traits to multiply and differentiate until their unique attributes are now the common necessities for survival.

That is true, and it is a good point. But the rate at which we are causing the extinction is much faster, and we do it consciously, causing harm to millions of species including ourselves. But you do have a point, I'll acknowledge that. We are not much different than a plague or a massive infection. Nevertheless, the fact that we do have intelligence means we have the moral obligation not to destroy other life and NOT to destroy at the rate we are.
