Question

Which hold more animal phyla coral reefs or tropical forest?

Answer 1

Counting only the economic value of fisheries, tourism, and shoreline protection, the costs of destroying 1km of coral reef ranges between US$137,000-1,200,000 over a 25-year period 
 Properly managed coral reefs can yield an average of 15 tonnes of fish and other seafood per square kilometre each year
 Southeast Asia's coral reef fisheries alone are estimated to yield US$ 2.4 billion annually
 More than 80% of the world's shallow reefs are severely over-fished 
 32 of the 34 recognised animal Phyla are found on coral reefs compared to 9 Phyla in tropical rainforests 
 Occupying less than one quarter of 1% of the marine environment, coral reefs are home to more than 25% of all known marine fish species
 58% of the world's coral reefs are potentially threatened by human activity 
 Coral reefs are found in 109 countries; significant reef degradation has occurred in 93 
 From 1876-1979 only three bleaching events were recorded, whereas 60 are on record from 1980 until 1993; in 2002 more than 400 events were recorded 
 We have already lost 27% of the world's coral reefs. If present rates of destruction are allowed to continue, 60% of the world's coral reefs will be destroyed over the next 30 years 
 More than 450 million people live within 60 kilometres of coral reefs, with the majority directly or indirectly deriving food and income from them 
 The total economic value of Indonesia 's reefs is estimated at US$1.6 billion annually 
 The total economic value of Philippine reefs is estimated at US$1.1 billion annually
 Coral reefs in the Malacca Straits have an economic value of US$563 million 
 Southeast Asia is considered the global epicentre of marine diversity. Its 100,000km2of coral reefs (34% of the world's total) are home to over 600 of the 800 reef-building coral species in the world 
 Indonesia and the Philippines hold 77% of Southeast Asia's coral reefs and nearly 80% of threatened reefs.

Answer 2

Animal phylum coral reef is worth more the value. Economist has valued the Great Barrier Reef at $56 billion. Yet this figure grossly underestimates the value of the reef, as it mainly focuses on tourism and the reef’s role as an Australian icon. When you include aspects of the reef that the report excludes, such as the ecosystem services provided by coral reefs, you find that the reef is priceless.
