GREG O'CONNOR (Labour—Ōhāriu): I can just imagine that member—the Hon David Bennett—standing in the Senate in the late 1890s in the United States when the horses were being phased out! The reason the horses were being phased out is that New York, like many of the other cities around the Northern Hemisphere—London, Chicago—were becoming absolutely overrun with horse excrement, not that much different perhaps than—I won't go there, as a member of my committee over there, but I think anyone will get what I'm saying. However, also, dead horses were left lying around. So, essentially, those cities were being absolutely overcome with pollution.
