To bring you bang up to date on environmental disasters, here's my last Blog Action Day post. Aussie experts in Queensland warn that the feral pig population is "out of control". As if drought weren't enough, Aussies are plagued by Sus scrofa (a rose by any other name). It's estimated there are 23 million feral pigs snuffling about the place, more than the human population. They're riddled with disease - the porkers, not the Aussies - and are unfit for human consumption. They gorge on crops from sugar cane to bananas, and their porker poo contaminates rivers and even threatens the Great Barrier Reef! They sound almost as bad as humans!
