Is Biotechnology Safe?

Biotechnology covers all types of actions and processes. As quoted above, we are now even “able to manipulate life and materials at the atomic level.” Some processes are less manipulative than others, less manipulative of nature as it is today. But others are quite a new level of man manipulating nature. Are all of these biotechnology solutions safe? Or are they planting new problems that may haunt us in the future?
