What is biotechnology? How would you explain biotechnology to a friend?

If I define Biotechnology in layman's words then it would be like this: ''Biotechnology is the use of technology in biological processes in order to create public welfare.''

Biotechnology is an amalgamationof all the sciences and uses highly principled techniques to either enhance the functioning and productivity of an already existing phenomena or to invent new things and phenomena by manipulating theorganisms n the micro level. In short, it is a field where we can makebig changes using small organisms.
