Environmental and human value ecosystems: coral reefs 

Coral reefs span more than 280,000 square kilometers and host tens of thousands of species in what many call rainforests.

Coral reefs are in many ways beneficial to the environment and humanity. They, for instance,

• Protect coasts from the effect of waves and storms;
• provide food and medical advantages for humans.
• Provide local populations economic benefits from tourism.

In addition, Tropical Coral reefs produce more than 30 billion USD in world products and services, such as coastal protection, tourism, and food.

The NOAA (National Oceanic and Ambient Authority) organization adds even more financial value. It claims that coral reefs produce an estimated $ 375 billion worth of financial services per year, including jobs, food, and tourism.

However, in recent years, global challenges to coral reefs have increased, and the worth of coral reefs may be even higher in the context of the wider environment.

 

The world’s coral reefs die. 

IUCN is the world’s oldest environmental organization, working throughout the world. IUCN, the international nature conservation union.

The Great Barrier Reef of Australia is perhaps the world’s finest maintained one. An Australian Agency report for 2009 (described below) provides worries for the future and the possibility of catastrophic damage to the ecosystem.

However, concerns have been expressed throughout the world concerning coral reefs for many years.

A 1998 assessment from the WRI estimated that human activities threaten up to 60% of the world’s coral reefs.

 

Global Coral Reef Threats 

A lot of the world’s marine biodiversity is endangered by events and actions like

• Overfishing, domestic contamination, global climate change. Coastal development.
• Ocean acidification caused by the excess emissions of carbon dioxide throughout the globe

Global mass coral bleaching causes climate change. 

The abovementioned coral reef status worldwide 2004 also points out (p. 21) that coral blackening and global climate change mortality have been a growing severe danger to coral reefs over the past ten years.

Bleaching may occur for several causes, such as Rob Painting on the leading Skeptic Science site.

Whitening isn’t new. The previous bleaching was typically located and modest to restore the coral period. However, as Painting also adds, large-scale coral bleaching seems to be detected, representing a completely new deterioration in the coral reef.

The high sea surface temperatures in 1988 and El Niño at the time, which led to global coral bleaching and death, are thought to have impacted nearly every species of coral.

In 2002, coral bleaching was the second-worst year after 1998.
