14% of coral reefs disappear in decade of climate change – Global Issue


In Sixth state of the world’s corals: 2020 reportExperts from the Global Coral Reef Monitoring Network, funded by the United Nations Environment Program (UNEP), have collected data from more than 30,000 scientists in 10 countries over a period of 40 years, over a period of 40 years, including two million personal observations.

It reveals that almost always, A sharp decline in coral coating, consistent with a rapid rise in sea surface temperatureIt has been found that these phenomena may increase as temperatures rise, indicating their weakness, and the planet continues to warm.

Invaluable ecosystem

Dynamic underwater coral cities support 800 species of hard corals and are home to more than 25 percent of all marine life.

Soft corals bend and swing in steep hills of hard corals to provide extra home for fish, snails and other marine animals.

And Reefs shelter the highest biodiversity of any ecosystem in the world, Makes them the most biologically complex and valuable on the planet.

Coral bleaching

However, when the water becomes too warm, the corals release their colored micro-algae, which turn the skeleton white. Some glow naturally by creating a protective layer of neon pigments before bleaching.

“Bleaching can be considered a ‘canary in coral mines’ version of the ocean because it is sensitive to the dangerous and deadly conditions of corals”, The condition of the coral wall Explained.

Acquisition of algae

The transition from coral to algae-inhabited reefs reduces the architectural complexity and structural integrity of these habitats, making them less biodiversity and providing fewer products and services to humans.

According to the report, tHard coral cover has been steadily declining here since 2010 The worst affected are South Asia, Australia, the Pacific Ocean, East Asia, the western Indian Ocean, the Gulf and the Gulf of Oman.

Precious coral

Although coral reefs cover more than 0.2 percent of the ocean floor in more than 100 countries, they value the safety of millions of people, coastal safety, health, food, and economic security.

And the value of the products and services they provide is 2. 2.7 trillion annually, including 36 36 billion in coral reef tourism.

However, coral reefs are under threat due to climate change, ocean acidification and land-based pollution; As well as silt from agriculture, marine pollution and excess fishing.

Maintaining the integrity and resilience of the coral reef ecosystem is essential Achieving the Sustainable Development Goals (SDGs) under the 2030 Agenda is an important part of the solution for the well-being and sustainable development of the global tropical coastal population. ” The condition of the coral wall.

Reef recovery

Despite this depressing assessment, there is still hope for the coral wall. They are significantly resilient and can recover in the absence of large-scale discomfort.

After a mass coral bleaching event in 1998, hard coral cover returned to pre-1998 levels within a decade.

If we stop and reverse the warming of the oceans through global cooperation, we will allow the coral reef to return from the shore.. However, it will take no less than ambitious, immediate and well-funded climate and sea action to save the world’s coral reefs, “the report said.

This year marks the beginning of the United Nations Decade for Ocean Science and Ecosystem Recovery for Sustainable Development, a campaign designed to protect our oceans through scientific advances and revitalize the planet’s growing ecosystem.

Moreover, the political leaders will attend the 15th meeting of the Convention of the Parties Conference (COP) on Biodiversity from Monday, April 25 to May, and again on Monday.

There, the world government will discuss the post-2020 global biodiversity framework to determine how humanity will live in harmony with nature in the next decade.
