What is acidification? Apart from being a powerful greenhouse gas, CO2 is also dissolved in large quantities in seawater and produces a phenomenon known as Acidification. Generally, when CO2 comes into contact with a water molecule, there is an increase in the concentration of H+ ions, which leads to a decrease of the pH levels … Read more
Oceana works to make acidification known as a serious consequence related to the impacts caused by climate change. The necessary measures should be implemented to halt and counteract this phenomenon. It is in fact essential that acidification be included in both EU policies and international climate conventions, for example the United Nations Conventions on climate change. … Read more

Open ocean aquaculture, without strict environmental regulation, poses a serious threat to marine life, fisheries, and the health of the oceans in general. Aquaculture facilities can be significant sources of pollution, including excess feed, fish waste and dead fish. This waste can spur excess algae growth, clouding coastal waters and altering seafloor ecosystems. The high … Read more
Mercury is a dangerous chemical, finding its way into the oceans and the seafood we eat. Mercury released to the environment from industrial sources ends up in our oceans, contaminating seafood. Because it builds up in wildlife through a process called bioaccumulation, animals high on the food chain carry the most mercury. Many of the … Read more
