What is the monetary value of the ocean ? [feedly]

Professor Robert Diaz of the Virginia Institute of Marine Science is a co-editor of "Valuing the Ocean" a major new study by an international team of scientists and economists that attempts to measure the ocean's monetary value and to tally the costs and savings associated with human decisions affecting ocean health.

The study estimates that if human impacts on the ocean continue unabated, declines in ocean health and services will cost the global economy $428 billion per year by 2050, and $1.979 trillion per year by 2100. Alternatively, steps to reduce these impacts could save more than a trillion dollars per year by 2100, reducing the cost of human impacts to $612 billion.

The world economy in todays dollars (without inflation) should be at least $200 trillion in 2050 and $400 trillion in 2100.

The $428 billion in 2050 would be about 0.2% of GDP in 2050 and 0.5% of GDP in 2100.

He notes that the study is unique in stressing the interactions between and among multiple threats, which include acidification, low-oxygen "dead zones," overfishing, pollution, sea-level rise, and warming.

So this includes global warming, pollution and overfishing.
