Coral Reefs: Global Distribution
Coral Reefs: Importance
Coral reefs support the livelihoods of millions of people.
Coral reefs supply seafood, building materials, sources for medicinal products, and draw in much needed tourism revenue.
Reefs also protect shorelines and communities from storms and erosion.

Coral Reefs: Importance
Coral reefs are an important source of food for hundreds of millions of people, many of whom have no other source of animal protein.
However especially reefs in developing countries are threatened and if human impact on reefs is not reduced there is a great danger, that some of the world's poorest people will lose an important source of nutrition, and in many cases their livelihoods.
http://www.starfish.ch/reef/hotspots.html#1
Coral Reefs: Importance
Despite their extraordinary value, coral reefs are deeply threatened by human activities and global climate change.

Coral Reefs: Threatened
Nations most socially and economically vulnerable to coral reef degradation
Haiti, Grenada, the Philippines, Comoros, Vanuatu, Tanzania, Kiribati, Fiji, and Indonesia.
28% of global reef systems
Reefs provide food, tourism, and coastal protection
Threatened by unsustainable fishing, population stresses, and global warming
Governments do not have capacity to protect them
Coral Reefs: Case Study Most Endangered Coral Region on Earth
Coral Reefs: Coral Triangle Region
Coral Triangle
600 different species of coral
3000 different species of fish (37% of world’s reef fish, 8% endemic)
Home to 6 of the 7 marine turtle species
and 22 species of marine mammals
120 million people live in the region and rely on the reef resources, income, and protection
Coral Triangle: Economics
The total annual economical value of natural habitats in the Coral Triangle including coral reefs, mangroves, and seagrass beds is an estimated US $2.3 billion
The commercial fishing industry of the Coral Triangle generates US $3 billion in income annually and supports millions of people in many costal villages.
http://www.coralscience.org/main/articles/climate-a-ecology-16/the-coral-triangle
Coral Triangle: Economics
Coral reefs, mangroves and seagrass beds are crucial breeding grounds for many marine creatures, including several commercially important species such as yellowfin tuna, bigeye tuna, skipjack tuna, Napoleon wrasse, and bumphead parrotfish.
Without these nurseries for large pelagic fish species, there would be nowhere for adults to spawn or for the fry and juveniles to grow and eventually reproduce, making the continued existence of these species impossible.

Coral Geographic is one of the projects now underway at Coral reef Research which will culminate almost all that is known about the biogeography of reef building stony corals.
Coral Triangle: Solutions
Marine protected areas can include several zones— “no-take”, sustainable use, research—which provide opportunities for both conservation and sustainable exploitation.
But there are still too few marine protected areas in the region. And even where they exist, often they are not effectively managed. This severely limits the ability of MPAs to replenish fish populations.
What we need are well-designed and well-managed networks of marine protected areas and locally managed marine areas. This is the key to preventing further biodiversity loss and fisheries collapse.
How/where do we design these marine protected areas?

Coral Triangle: Solutions
Sustainable fishing
International laws and standards support sustainable fisheries management, and are applicable to tuna regional fisheries management organizations (RFMOs) and their member states. But in reality, tuna RFMOs have been unable to prevent overexploitation of tuna, rebuild depleted stocks, or protect the wider ecosystem.
How do we address the problem of unsustainable fishing?
http://wwf.panda.org/what_we_do/where_we_work/coraltriangle/solutions/sustainable_tuna_fisheries_coraltriangle/
Coral Triangle: Solutions
In the Coral Triangle, the impacts of bycatch have been devastating. Populations of nesting marine turtles have declined by as much as 90% in some areas
Overfishing of sharks in longline fisheries targeting tuna has endangered many species and in shrimp fisheries, juvenile 'trash fish' can outweigh the catch of targeted shrimp by more than 10 to 1
Fishing gear—longlines, gillnets, and trawl nets, not selective
How do we implement and enforce the use of better, safer technologies for fishing?
http://wwf.panda.org/what_we_do/where_we_work/coraltriangle/solutions/tackling_fisheries_bycatch/
Coral Triangle: Status
40% of coral reefs and mangroves destroyed in the last 40 years
Only 1% of protected areas effective in stopping coral degradation
Coral Triangle will disappear at a rate of 1-2% every year
In 40 years, the Coral Triangle may collapse and vanish
Easy Ways You Can Protect Coral Reefs
Conserve water and energy
Reduce Pollution
Buy renewable or biodegradable products instead of plastics
Support reef-friendly businesses
Wear a swim shirt for sun protection or natural sunscreens
Do not step on or harm coral
Volunteer for ocean and rivers clean-ups!
Caribbean Reseeding Project
Conservation Infogram: The Coral Triangle
How/where do we design these marine protected areas?
How do we address the problem of unsustainable fishing?
How do we implement and enforce the use of better, safer technologies for fishing?
Pick one of the three questions and create an Infogram highlighting the potential solutions to the problems.
