The worst flooding in 130 years has turned eastern Australia into a giant wading pond, killing dozens of people, wiping out crops and livestock, destroying tens of thousands of homes and shutting down hundreds of towns and cities.
At risk at the edge of Queensland’s shores is the nearly extinct dugong – the prehistoric marine mammal that looks part sea lion, part bulldog – that feeds off the sea grass that line the coast. Unfortunately the floodwaters are inundating those feeding grounds with sediment, topsoil, rubbish and all sorts of debris on top of toxic industrial and agricultural run-off.
Environmental officials are concerned that the floods will similarly destroy wetlands, coral reefs and marine parks along Australia’s coast. Fresh water kills coral reefs, though it remains to be seen what the long-term effects will be from this particular flood.
