Speech On Ocean Acidification

An ocean it is from the Greek word which is Okeanós. Roughly, 97% of the Earth’s water supply is from the ocean. Besides that, the ocean also has many kinds of function. The ocean could affect the weather and also the temperature. For example, absorb incoming solar radiation to moderate the Earth temperature or stored as heat energy. The heat that being absorbed by the ocean is mostly during winter and it cools during summer. This could be done by the ocean through moving always then distribute the heat around the globe.

The earth was covered almost 70% of it with the average depth of 12200 feet approximately 3720 meter. While, the deepest point of it are 36198 feet or approximately 11 033 meter in the western Pacific, Mariana Trench. Therefore,

One of the major threats is Ocean acidification. As the world kept busy on catching up the technology, they somehow forget how to preserve the environment at the same time. For a million years, the ocean played its role to maintain and stable the acidity level in the earth. However, as time pass by, the ocean is unable to stabilise the acidity level due to too high of carbon dioxide (CO2). This situation occurred when the atmosphere that contain carbon dioxide (CO2) in which are then being absorb by the ocean in order to preserve human from exposed to the harmful emission.

The amount of carbon dioxide (CO2) in the atmospheric is too huge lead to the greatest impact in building up the corals for the reef as it being absorbed by the ocean. Earth’s atmospheric concentration CO2 is now higher than it has been for more than 800000 years (Luthi et al., 2008), and the amount is expected to keep on climb up at an accelerating rate in which lead to the rising up of the temperature. Furthermore, Reef could not exist without the existence of corals. Their rate of growth is getting slower and if it is being left unchecked, it is surely will be erode away since it soon will stop

The scale can be read through 0 for strong acid to 14 for strong alkaline while the scale of neutral is 7. Normally, the oceans are alkaline. In 1750, the pH level of the ocean is about 8.2. However, the ocean surface acidity level has rose up by 30% due to the huge amount of carbon dioxide.

The emission of carbon dioxide (CO2) his had affected the atmosphere, and as the result it leads to climate change and global warming. Ocean acidification is one of the process are growing concern from the scientist, the government policies also those who make decision in which had cause to the damaging the fish, human activities that related to the seas also the tourism. Besides that, the marine organism may disrupt the food web. Furthermore, it may also alter the composition of the species also the ecosystem. If these situations keep on growing, the billions of people all over the world need to face marine-based diet since it no longer safe anymore due to the emission rate are equal to the ocean
