What would be a great conclusion on my vegetarianism speech?!
Answers: i support vegetarianism
Remember to reinstate key ideas from throughout the speech to provide closure and tie it all together. Try to make the finale of the speech personal, something that is lasting - maybe tie it to the listeners somehow. Talk about the incredible health benefits, the benefits for the environment and about how many great minds have already made the connection and were vegetarian - Ghandi, Leonardo da Vinci, Plato and many more.
It is hard to say without knowing your entire speech. If it sounds right in context to the rest of the concluding paragraph, then go with it.
