The Great Barrier Reef is facing a new challenge: Dirty Water.
Scientist have warned it at greater risk than ever. Run-off
from the recent flood in Australia is spreading from the coast with the
potential to reach the fragile reef. The flooded water includes the sediments
from the shore. It is being feared by the scientists that this may block out
the sun affecting the photosynthesis of the algae. The floodwater may also
contain pesticides that could prove extremely damaging to the reef.
Dr. Frederieke Koon from the Australian Institute
of Marine Science told the BBC the floodwater contains nutrients that have boosted algae growth in some areas, turning the water into “a thick
blanket of green”. He also said that a bit of wind and wave action can break
the plumes up quite quickly, but that area literally had no wind so they’re just
sitting there hanging.
The US National Oceanographic and Atmospheric
Administration forecasting in October 2018 has estimated that the entire 130,
000 miles square system is at high risk of bleaching.
