Carbon dioxide has been increasing rapidly over the years and our oceans have been absorbing one third of the emissions overall. Oceans are said to be the largest carbon sinks in the world but the more carbon dioxide they absorb the more acidic they are becoming (2). This change in our oceans acidity will affect our planet 's global climate change and also our marine life overall. Ocean acidification is the process of our ocean taking in carbon dioxide emissions from our atmosphere and turning it into carbonic acid which leads to a lower PH level meaning higher acidity for our oceans (1)(2). Over the past 300 million years our oceans acidity has been at 8.2 units of acidity and it has gone down to 8.1units (4).
When carbon dioxide concentration in waters is altered so is the concentration of other elements such ad nitrogen and iron which are key ingredients to survival for microbial communities. That is one consequence but this process could affect the calcifiers drastically. These organisms build their own bodies with calcium carbonates. But because of the high CO2 concentrations the concentration of calcium and carbonate ions are drastically low therefore the organisms which rely on calcium carbonate cannot survive. This was clearly visible when Elizabeth went to those sea floor vents which were pumping carbon dioxide.
The ocean acidification is probably the most important issue on our planet today. I think the ocean acidification is the most important issue today because ocean acidification affects all life on earth. For me, counter the ocean acidification needs to be a priority now because it was directly connected with the last few mass extension. If we succeed to stop the ocean acidification, we are going to resolve a lot of problems who are going to be linked with this issue. I’m sure the cause of the ocean acidification is that we are changing the environment very quickly and now, we are converting hundreds of millions of years of fossil fuel, burn it, and turn it into carbon dioxide.
The carbon dioxide in the air rises due to fossil fuel emissions; therefore, more of the gas goes into the ocean’s water. That makes the coral’s habitat more acidic, which can make it harder for reef-building creatures to build up the hard skeletons. And if that isn 't bad enough, the runoff chemicals from farms and lawns are adding to the problem by changing the water’s natural composition. A oil spill in 2010, caused by a Chinese coal-carrying ship, went through the coral reef, leaving almost 2 miles of oil to mix with the ocean water (Zimmerman). As more and more water is becoming contaminated with pesticides and chemicals, it is becoming even harder to stop the corals from dying.
Calculations for tourism for the year of 2015 are unavailable at this time, but for the year of 2014, the reef received a total of 2.19 million visitors. It is a well – known piece of information that there is a global climate change going on where there is a rise in CO2 in the atmosphere due to higher emissions of fossil fuel and more deforestation occurring. The ocean then absorbs more of this CO2, which in turn raises the acidity, which in turn creates a poor environment for the coral to live and recover from bleaching that has already occurred. This change in acidity also affects the calcium carbonate that corals use to build themselves. (“Climate Hot Map- Global Warming Effects Around the
Another effect of climate change is ocean acidification. The amount of carbon dioxide absorbed by the upper layer of the oceans is increasing by about 2 billion tons per year. Now, the problem today is that some people, at least those who do not deny the issue of climate change, see climate change as only an environmental issue. However, it is important to realize that climate change is not only an environmental issue, but also a major health issue as it can easily affect a significant number of individuals, especially those in third-world countries. In countries like Bangladesh and the Philippines, the climate restrains the people of the country to grow crops and make food for themselves.
In “Is Fish Farming Safe?” Terry McCarthy states that the current way of fish farming is ruining our water and eco systems by dumping waste. Elizabeth Kolber essay “The Acid Sea” discusses about the carbon dioxide we are pumping into our oceans, and Susan Casey “Our Oceans Are Turning into Plastics… are you?” focuses on how we are dumping plastics and garbage into our oceans. While despite these author’s talking about different topic they all agree about future ramifications of having wastes in our oceans and waters.
Moreover, the total amount of toxins and debris discharged by human beings is incredibly increasing in today 's world. Most of the waste produced on land is either intentionally or unconsciously discharged into the oceans. Marine pollution and aquatic debris can utterly destroy the oceans causing extinction of the marine creatures. Innovative techniques should be implemented in the law to prevent the marine environment from any further damage. In order to improve the marine environment, the government and the Environment Public Authority of Kuwait should take immediate actions that can influence the society and help in minimizing aquatic debris and pollution.
Ocean Pollution DBQ Did you know that every year, eight million metric tons of plastic is dumped or somehow ends up in the ocean (Doc. 1)? The following sentences will talk about what people are doing to pollute the oceans and how they are making the pollution better. Humans are the biggest threat to animals in the ocean because they litter so much (OI). Sometimes, people litter without even knowing they're littering.
Almost 30% of the South African population lives on the coastline (Taljaard et al. 2006), which has led to the urbanization of the coastlines and which then led to the industrialization of these areas. This industrialization has led to high pollution levels. The pollution that is being emitted daily from the coast lines around South Africa can and is causing damage to the marine ecosystem, such as crippling the fish populations and coral bleaching. It is also ruining the amazing marine biodiversity that South Africa has.
