The National Center for Atmospheric Research (NCAR) said that by 2030 the ocean will possibly have an alarming level of depleted oxygen, which could affect the marine life and human resources as well. Again, climate change is behind this news. CREDIT : Image courtesy Joe Raedle Loss of oxygen in the ocean is one of the serious side effects of climate change, and a major threat to marine life. According to a study published in the journal Global Biogeochemical Cycles , "a warming climate can be expected to gradually sap the ocean of oxygen, leaving fish, crabs, squid, sea stars, and other marine life struggling to breathe". CREDIT: Image courtesy Matthew Long, NCAR Fish and other marine animals survive underwater because of the presence of oxygen, with reduced oxygen their potential to thrive will be compromised. Besides, the oxygen level is important to regulate metabolic and biogeochemical processes that happen in the ocean. As our ever-warming atmosphere heats the

It´s about time to discuss in this blog the role that people play in fisheries management , after all , it is impossible to untangle fisheries from their human context : fisheries have substantial social and economic importance. Fish is one of the most important renewable natural resources supporting human well-being and food security. Unfortunately, as discussed previously here and in multiple of our previous posts, global fisheries are currently under-performing by the combined impacts of overfishing, degradation of ecosystems, pollution and climate change. It is easy to see that humans are the main, if not the sole cause of losses in our fish stocks. We behave as if we could take whatever we wanted out of the oceans , returning everything we do not need anymore without limits. Such destructive interaction only grows with an increasing population of consumers. However, if we depend heavily on fisheries resources, how smart are we to be using them in such an unsustainable way? If w
