Answer:
Every object you touch, see, taste, or smell during the day is a chemical, no matter what the signage says on some containers of “Contains no chemicals.” It would seem to me that knowing as much as possible about these objects would be of benefit to mankind, and hence chemistry becomes of great advantage to us all. The science of chemistry really has no disadvantages, but we humans can be at a disadvantage if we do not bother to learn, for example, that cyanide should not be part of your diet.
