Interview: Queensland Minister for Environment and Heritage Protection, and Minister for National Parks and the Great Barrier Reef – impressive analysis that main problem is turbidity, inspecting 6 year old trial sites, with 6 different treatments, identifying that, as soon as surface turf is broken by cattle, below, there’s big depth of very fine sediment soil, eroded away by heavy rain. Lab test shows density and long life turbidity. Of course, Greg Hunt has always said that problems for reef are neither sea level rise, nor warming, nor acidity but run off from farming. His plan has ben to reduce run-off of fertiliser, herbicide and pesticide, disregarding that scientists, from Barrow Island WA to Cooktown have been trying to persuade him that turbidity is the culprit. Since corals are strange mix of plant and animal, blocking of sunlight stops plant side photosynthesis and blocking of micro food entries starves animal side. Regardless, you can be sure that Greg is “absolutely confident…” that his plan will deliver, to save us from “Critical/Endangered Status” pending with UNESCO.
