You need to describe the world as a new bliss. "This is utopia with my idea adopted." "This is the way the world is going to look, when we join together and we solve this big problem." You need to use that as your ending, in a very poetic and dramatic way.
Hay que describir el mundo como una nueva dicha. "Esto es una utopía con mi idea adoptada". "Esta es la forma en que se verá el mundo, si nos unimos y resolvemos este gran problema".
