The California coast is a thriving ecosystem, both beneath the sea and in the cities that line its shore. For the purposes of our discussion, we will focus on mussels as an example species. Mussels, as we speak are being harmed by ocean acidification, and the damage is becoming more and more costly to our ecosystem. Global climate change, more commonly referred to as global warming, is an important factor in ocean acidification. At its most basic, climate change is the result of previously unheard of levels of carbon dioxide entering the atmosphere and creating a greenhouse effect within the earth’s atmosphere. This causes the average temperature of the planet to increase over time. The full effects of this kind of temperature increase are still being explored, but it is already clear that our planet is being harmed as a result. Ocean acidification is an extension of global climate change. It is the result of about a third of the carbon dioxide in the air seeping into the earth’s oceans. Ocean Acidification Our ocean, consisting of approximately 70% water and 30% land, is a vast surplus habitat that is unexplored and uncontrollable. Although humanity has achieved much in advancement in technology, resources, food, and more, nature is a factor that humanity cannot predict and manipulate. Nevertheless, our society has caused a grand shift in our global climate, a shift that is costly to our environment. One major reason to account for this shift is the utilization of fossil fuels into the environment. This process creates a multitude of carbon atoms that are released into the atmosphere, which is detrimental to our environment. To be exact, global warming is the process where there is an increase amount of greenhouse gases (such... ... middle of paper ... ...ze the importance of this issue and the urgent need for a resolution to climate change.

...oceans. Anthropogenic systems such as the combustion of fossil fuels since the industrial revolution have greatly increased the rate of acidification to levels where negative impacts ensue. Negative impacts occur both to marine organisms that rely on certain water conditions to maintain vital functions and the environment which is damaged by highly acidic waters. There is great variation in the acidity of each of the oceans, differences caused by the chemical composition of the ocean and biogeography. Understanding of the potential impacts of ocean acidification is relatively new to the scientific community and therefore little is known on how to counteract anthropogenic influences. Although reducing the amount of carbon dioxide produced will in turn reduce the lowering of the oceans acidity levels and reduce negative impacts on the environment and marine organisms.

Excessive nutrients from agriculture, development, and industry are harming the Chesapeake Bay. These excessive nutrients harm the habitat for many of the bays species. On top of the habitat being depleated, overfishing and diseases are also hurting the bays species. Nutrient loads can be reduced with the help of lawmakers to put a cap on the emissions allowed in the environment. If this is done the dead zone will start to recede, but the time and money need to be spent in order to save the bay.
With carbon dioxide levels continuing to rise over the past few decades (fig. 1) and now into the future, concern has been brought to what is happening to the carbonate chemistry of the oceans. Because of these changes in chemistry, the ocean is becoming more acidic. Along with climate change, ocean acidification may be one of the greatest threats to our planet. The higher the ocean’s acidity level goes, the lower the calcium carbonate levels will drop. Even though this is a big scale issue, my goal is to focus on and underline what these changes will mean for the marine life that depend on the calcium carbonate in seawater. I will go in depth with specific regards to a study regarding pteropods or sea butterflies.
Ocean acidity will spoil marine ecosystems if it remains persistent. Preserving sustainable fishing industries will become unmanageable if the carbon dioxide absorbed by the world’s oceans is not considerably abridged.

The use of fossil fuels has greatly increased the amount of atmospheric and oceanic CO2 to a point where it’s ruining the natural flow of the world; the earth’s temperature is rising. As a result, the polar ice caps are melting causing the seas to rise. With only a 1 meter increase in sea level the United States alone could lose over 10,000 square miles of land, and thousands of houses will be destroyed. The effects will be just as prominent around the world: many islands will become submerged, 17% of Bangladesh will be underwater, and tens of thousands of people will be displaced (“Global Warming” 3).

To exemplify the ever increasing degree of pollution, I will be focusing on the Santa Monica Restoration Project. This project is an ongoing effort to maintain a clean and healthy environment in and surrounding the Santa Monica Bay so that plant and animal life are able to thrive. Unfortunately this project is continuously challenged by numerous pollutants. Pollution is a simplified way of classifying a multitude of harmful acts and elements. The Santa Monica Bay experiences pollution created by auto and homeowners, oil spills and leaks, gasoline and paint contamination from boats, wastewater from two local sewage treatment plants, litter and construction sediment. The goal of the restoration project is double fold. Number one, to clean up the bay in order to bring back plant and animal life that has either died or fled to other habitats, and two to make the individuals and companies who cause the contamination aware of the harmful acts they are engaging in daily.

There needs to be a reduction if not extinction with the increasing amounts of carbon dioxide, methane, chlorofluorocarbons (CFCs), hydrofluorocarbons (HFCs), per-fluorocarbons (PFCs) and nitrous oxide into the atmosphere because it is directly affecting global warming. The combustion of fossil fuels and greenhouse emissions mainly contribute to the increase of these gases. The longer we go without solving this global problem the more conflicts we will have in the future. Although global warming does make the earth warmer there is more to worry about than heating to death. Major concerns revolve around effects on agriculture, water resources, ocean level and coastal regions, and disease. Many scientists and experimenters still disagree with global warming using excuses such as ‘primitive’ climate models, which predict global warming trends, can not accurately simulate the Earth; it is too difficult because there are thousands of variables to consider. With the issue of global warming alternative sources of energy are looked for. “Data indicates that hydrogen is [the] only suitable future fuel.” (Williams, 102). Many scientists agree, but how long will it take for us to get there?
The burning of fossil fuels has greatly harmed our environment and is a leading cause as to why climate change has become such a threat to our way of living. In May of 2013, the carbon dioxide levels in the atmosphere reached 400 parts per million, an increase of more than 40 percent since the beginning of the Industrial Revolution. This could cause the Arctic Ocean to be nearly ice-free during the summer by 2020(Overland and Wang, 2013).
