Performing arts such and singing, dancing and acting are HUGE parts of the entertainment industry. In fact, they are all what make up the entertainment industry. Without it there is no such thing as the entertainment industry. I just asked this question because I know that there are some people who think that performing arts is a waste of people's time and they should spend their time on more "practical" things such as maths or science which I personally think is absolutely ridiculous! In fact, I think performing arts is underappreciated already. We need to give it a better name to those ignorant of it!!!
