Health of Oceans Get Grade of 60 out of 100

The newly created Ocean Health Index has given the health of the world’s oceans a score of 60 out of a possible 100.

The index was developed through the collaboration of more than 60 scientists and marine experts from around the world. It defines a healthy ocean as one that sustainably delivers a range of benefits to people both now and in the future. A healthy ocean is one that can maintain or increase benefits (food and services) in the long term, without jeopardizing the health or function of the web of life that underlies the ocean.

Researchers used a wide variety of existing marine data, measuring everything from the percentage of live coral covering tropical coral reefs to the percentage of coastal people served by adequate sanitary facilities and the kilograms of shrimp grown on aquaculture farms.

They crunched over 200 sets of marine data, and measured each country’s score against reference points that set standards of maximum sustainable use. A goal score of 100 would mean that the evaluated system reached its defined target, sustainably delivering all of the benefits that it can in the present and likely near future. A low goal score means that the maximum benefit is not being obtained and/or is not being obtained in a sustainable way.
