Fast facts: why coral reefs are important to people | WWF

Calculating only the economic value of fishing, tourism and coastline protection, the cost to destroy 1 km of coral reefs is between $ 137,000 and $ 1,200,000 in 25 years.

Properly managed coral reefs produce an average of 15 tons of fish and other seafood per square kilometer per year.

While there are 9 Phylas in the tropical rainforest, 34 recognized animals, Phyla 32 are found in coral reefs.

Coral reefs account for less than a quarter of the marine environment, accounting for over 25% of all known marine fish.

Between 1876 and 1979, only three bleaching cases were recorded, compared to 60 records between 1980 and 1993, more than 400 records were recorded in 2002.

27% of the world's coral reefs have been lost. If the current damage rate continues, 60% of the world's coral reefs will be destroyed in the next 30 years.

Within 60 kilometers of coral reefs, more than 450 million people live, most of whom receive direct or indirect food and income.

Southeast Asia is considered to be the world center of marine diversity. Over 100,000 square kilometers of coral reefs (34% of the world's total) are home to more than 600 coral reefs of 800 world reefs.

In Indonesia and the Philippines there are 77% of coral reefs in Southeast Asia and nearly 80% of endangered species coral reefs.

Unfortunately, corals are decreasing seriously. According to the conservation organization of the World Wildlife Protection Organization (WWF), two thirds of the world's coral reefs are being threatened seriously, and a quarter of coral reefs are considered irreparable. There may be hope as a new technology that provides opportunities to revitalize coral reefs at an astounding rate. Approximately 94% of Indonesian coral reefs were seriously damaged at the 2000 International Coral Reef Symposium. These include the Pemuteran Gulf where coral reefs that were once thriving were essentially barren. As a result, Biorock technology can recover coral reefs in more than 10 years.

As part of the global industry, coral reefs have made a great contribution to the world economy. In fact, some countries, like the Caribbean countries, receive revenue primarily from activities centered on coral reefs. Unfortunately, the number of coral reefs has declined recently at an amazing rate. This unprecedented reduction, such as irresponsible destructive fishing methods, contamination from neighboring areas, mining coral mining, excessive erosion from coastal area artifacts, poses a serious threat to coral reef function I am in

People do not know how important coral reefs are. Approximately one quarter of marine organisms rely on coral reefs, and about 1 billion people depend on coral reefs for food and income. So, they are very important, and people did not rotate completely about the results of potentially losing coral reefs. Through 50 coral reef projects, I am looking for coral reefs that are hard to be affected by climate change. We now lose most of the remaining coral reefs. This is given. About 10% of reefs can be saved. Therefore, what we need to do is to identify coral reefs most unlikely to be affected by climate change, protect them from local influences and strengthen protection of these critical areas as catalysts for all coral reef protection It is to do.
