Bacteria

Bacteria, those tiny, unseen organisms, provide almost half of the oxygen we breathe. There are 1.8 million known named species of bacteria. How much bacterias on earth you might ask? How about 10 followed by 30 zeroes. Bacteria is also used to create lifesaving drugs. Bacteria for the most part is a good thing for us humans. And just in case the Martians attack us, remember the ending of H. G. Wells book (and movies!) "War of the Worlds." In the end, the Martians are defeated not by science or the military, but by bacteria germs-or, to quote H.G. Wells, "the humblest things that God in his wisdom has put upon the earth."
These are the days my friend.
