What is the monetary value of a healthy ocean?: Scientists have attempted 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.
