From my perspective debating is an art of organizing and delivering thoughts quickly and effectively in order to change people's perception. It not only broadens one's knowledge but also develops problem solving skills, analytical thinking, and ability to work in a team and interact with other students. ability to deliver ideas concisely is important for economists, what I am majoring in.

While the above is smoother grammatically, you could still revise for style and content to make this essay stronger. For instance, if you could give specific examples of how debating has broadened your knowledge and developed your problem solving skills, that would make the essay more interesting.
