The report shows that the global coral decreased by 14%

A report released on the 5th of the Global Coral Reef Network showed that the number of coral reefs in the global coral reef decreased by 14% in 2009 to 2018.

Reuters said that this is equivalent to approximately 11,700 square kilometers of coral reef.

This is the sixth issue released by the Global Coral Reef Monitoring Network on the status of the global coral reef, which is the first report since 2008.

The report summarizes nearly 2 million observations in 73 countries and regions from 1978 to 2019 to the first quantitative analysis. The scale of the survey is the same in the same category. This report shows that between 2009 and 2018, the number of corals in different parts of the world is large, of which East Asia has a minimum, 5%, and the Tropical area of ??the eastern Pacific is as high as 95%.

According to the report, the coral faces the survival crisis.

One of the reports of the Australian Oceanology, Paul Hadistri, director of the Australian Oceanology, said: "Climate change is the greatest threat to the global coral reef … Coral significantly problem reduction trend, we can expect, with the climate Warming, this trend will continue. "The report said that the coral reef is an important marine ecosystem. Although only the world’s% of the submarine, at least 25% of marine species rely on coral reefs, and related to hundreds of millions of people. The coral reefs offer the annual commodity and service valuation to trillion, including $ 36 billion in coral reef tourism.

However, coral reefs are one of the most vulnerable ecosystems to interfere with human factors on earth. Among them, the impact of water warming initiated by global warming is the most serious, resulting in a large number of corals. The report pointed out that large-scale coral whitelation is the maximum damage factor of global coral reef.

According to reports, marine pollution, excessive fishing, coastal development is not sustainable, etc., also threatening coral reefs.

However, the report pointed out that in view of the increased number of corals in 2019, if the survival threats faced by coral reef, the number of corals is expected to return to the past.

According to AFP reported that the average temperature of the world has increased degrees Celsius before industrialization, the Intergovernmental Climate Change Special Committee has previously predicted that if this number reaches degrees Celsius, 70% to 90% of coral will die.
