After several warnings about the Reef's condition, the Australian government stated that stopping nitrogen runoff from farms and preventing fine sediment from getting into the ocean would help the reef survive. Many of the measures in its Reef 2050 Plan to help the reef survive are in the process of implementation, but climate activists claim that the government is not committed enough as evidenced by its approval of a new coal mine.
"Virtually all of the relevant science indicates the Great Barrier Reef is in decline."
The water quality in the Reef is diminished by erosion from weather, mining, and deforestation that allows fine sediment to be swept into the ocean. Erosion is hastened by the removal of native plants that hold the soil together, and mining, agriculture, and deforestation all contribute to the ease with which rain and other runoff can pick sediments up.
