I absolutely agree with that sentiment as well. While we, as a species, are relatively inconsequential, Earth is all we've got (for now!) and it's a special, precious, thing indeed.
Important to whom? The universe itself is incapable of assigning 'importance', so saying that something is unimportant to the universe is just as wrong as saying something is important to the universe. Humans are important to humans, and that's what matters. If only I think I'm important, then I am, to me.
