L’océan représente 97% de l’espace physique habitable de la planète et joue un rôle central dans le maintien de la vie sur Terre. Depuis les années 2000 que des efforts considérables et spécifiques ont été déployés pour mieux faire connaître et comprendre les conséquences des émissions de gaz à effet de serre sur les océans. Le dioxyde de carbone émis par les activités humaines conduit les océans vers des conditions plus acides, phénomène connu sous le nom d’acidification des océans.

El océano representa el 97% del espacio físico habitable del planeta y es fundamental para mantener la vida en la Tierra. Solo desde el año 2000 se han realizado esfuerzos importantes y dedicados a aumentar la sensibilización y comprensión de las consecuencias de las emisiones de gases de efecto invernadero en los océanos. Actualmente sabemos que el dióxido de carbono que emiten las actividades humanas está dando lugar a condiciones de mayor acidez en el océano.

The ocean represents 97% of the physical habitable space on the planet and is central to sustaining all life on Earth. Since 2000 significant and dedicated effort has been directed at raising awareness and understanding of the consequences of greenhouse gas emissions on the ocean. Carbon dioxide emitted by human activities is driving the ocean towards more acidic conditions.

The development of this second edition of these guidelines was in part a response to evidence of the widespread incorrect application of the categories to marine protected areas (MPAs). Marine management and sustainable fisheries management are critical elements of good oceans management, but are not the same as protected areas management, where the primary focus is conservation of nature.

The ocean on which Earth depends for relatively predictable weather, temperature and provisioning of goods and services is now changing more rapidly than it has for millions of years. This is due to human interactions with the  atmosphere and land, and increasing expansion of the footprint of human impacts across the ocean.
