Diana: But we aren't going to go extinct tomorrow. There are still plenty of creatures left in the world.
Matthew: I have sense of time than you. When humans talk about climate change, that's exactly the argument they use. "Oh, the polar ice caps will take so many years to melt. Who cares?" I remember when the Thames iced over every winter. I used to skate on it. You're right, though. It's not going to happen immediately tomorrow, but it's already begun. One day there'll be just one species -- humans. At first, they won't notice the difference because they never notice us, but gradually, eventually, they'll come to see that all the magic has seeped out of the world. They'll look around them, and everyone will be the same.
