Thinking about artifical and natural. How would you define it? Example: artifical sweetners, invertro fertilization. There is no word count with this topic.

Better yet - How do you respond to this student:

For me natural is something that occurs in nature where as artificial is something that had to be made or processed by man. When considering the question above where does inveitro fertilization fall into this. Should one consider a child who was conceived with the help of a laboratory artificial? I do not think so. Depending on the method the artificial part of this would be how the natural process of childbirth is started. Once this is done the body naturally takes over and the end product is a living and breathing human being, not an artificial human. What does the rest of the class think about this example?
