Australia has pledged A $ 500 million (£ 275 million, $ 379 million) to protect the World Heritage-listed Great Barrier Reef.
In recent years, the reef has lost 30% of its coral due to bleaching associated with the rising sea temperatures and damage caused by crowns of thorns.
The funds will be used to reduce the flow of agricultural pesticides and improve water quality.
Part of the money will be used to help farmers near the reef to change their practices
Dangers to the reef include "large amounts of sediment, nitrogen and pesticide residues" and the crowns of thorns, said Environment Minister Josh Frydenberg.
The reef can be seen from outer space and was listed as a World Heritage Site in 1

In 2017, the organization decided that the Great Barrier Reef would not put on his official list of 55 World Heritage sites "in danger".
The unprecedented coral bleaching has in recent years two-thirds of the reefs, aerial photography from the year 2017.
Crown of Thorns starfish are one of the most harmful creatures that attack tropical coral reefs, as they are voracious predators that deliver the contents of their stomach to the coral.
Digestive juices then liquefy the coral for consumption. A single single starfish can extinguish large areas of a reef.
The reef is actually a huge cluster of thousands of smaller coral reefs that stretch from the northern tip of Queensland to the southern city of Bundaberg.
Conservationists have welcomed additional funding, but said the government needs to focus on the climate
"The Great Barrier Reef can not be 'conserved' without reducing CO2 emissions – meaning no new coal, no oil or gas, "said Greenpeace Australia Pacific's CEO on Twitter.
Australia's Secretary of State Julie Bishop, on the other hand, stated The Australian news agencies were world leaders in the management and protection of their reefs.
Australia is considered one of the world's worst polluters of greenhouse gases.
In 2015, Australia had announced to cut greenhouse gas emissions by 26% and 28% below the level of 2005 before 2030.
