Thoughts for a Countdown

In the article " Thoughts for a Countdown", it mentions how if something is foreign, we will protect ourselves against it, eventually killing whatever that is foreign. i do believe this is true because we are so scared of what is out there after discovering practically the gist of what earth has to offer. It has become "attitude toward life, our obsession wiht disease and death, our human chauvinism" (7). It has become so built in that we will destroy most things. We always take thing to another level no matter if its good or bad. We may be too extreme. Even though with all the knowledge we have ," it has been estimated that we probably have real knowledge of only a small proportion of the microbes on earth, because most of them cannot be cultivated alone. This shows how little we assume we know and how much is out there. It does keep us on our toes as we learn new things and discover our world.
