"Life on this earth is not only without rational significance, but
also apparently unintentional. The cosmic laws seem to have been set
going for some purpose quite unrelated to human existence. Man is thus
a sort of accidental by-product, as the sparks are an accidental by-
product of the horseshoe a blacksmith fashions on his anvil. The
sparks are far more brilliant than the horseshoe, but all the same they
remain essentially meaningless. They constitute, at best, a disease of
the horseshoe--they involve a destruction of its tissue. Perhaps life,
in the same way, is a disease of the cosmos."

Arguing for the agreement of this side:

If we sum this up man is a parasite. This is true as man goes along he destroys everything and everywhere he goes jsut a parasite destroys crops and moves on man destroys the earth and goes to another place to destroy. Man has gotten so mixed up along the way that he just creates "newer" and "better" ways to kill the place he resides in.

Arguing against this side:

Man cannot be just a parasite because man has created irrigation and farming. The thing that seperates us from parasites is we try and clean up after ourselves. Man tries to better himself rather than just moving on without any though

Arguing for:

Although man tries to clean up he creates the mess which cannot be fixed. When creating farming man destroys wood lands. Man is the inevitable end to all things

Arguing against:

But, man is trying to reach other planets to start over and fix the situation

Arguing For:

By traveling to a new place he is just killing more
