One of the things I really like about Senator Ludlam is that, compared to some of his colleagues in the Greens, he is an optimist. When I hear contributions from some of his colleagues in the Greens, especially in some of the climate change and environment debates that I also have carriage of in this place, I find myself leaving rather depressed, concerned that the world is going to come to an end, possibly as early as tomorrow morning.
