You Can't Live Without Them

Bacteria have been here for over 4.5 billion years. They lived on earth a 
lot longer than we have. They were the only life on the earth for 80% of 
earth's time-line. They seem to be in charge of much of the life here on 
this planet. They can destroy life with their toxins or they can help life 
to proliferate with their unique ability to emulsify fats, to break down 
cellulose, etc.

No organism can grow and flourish without the presence of bacteria.
