When the ocean heats up the the water starts to acidify making fish that eat off the coral reefs die off which makes the smaller fishes predators die off and when they release no oxygen after all of the fish die off they stop releasing oxygen humans will die off.
When CO2 release into the air the ocean absorbs it
How Does The Ocean have to do with Human Health?
Our ocean and coasts affect us all—even those of us who don't live near the shoreline. Consider the economy. Through the fishing and boating industry, tourism and recreation, and ocean transport, one in six U.S. jobs is marine-related. Coastal and marine waters support over 28 million jobs. U.S. consumers spend over $55 billion annually for fishery products. Then there's travel and tourism. Our beaches are a top destination, attracting about 90 million people a year. Our coastal areas generate 85 percent of all U.S. tourism revenues. And let's not forget about the Great Lakes—these vast bodies of water supply more than 40 million people with drinking water. Our ocean, coasts, and Great Lakes serve other critical needs, too—needs that are harder to measure, but no less important—such as climate regulation, nutrient recycling, and maritime heritage. Last but not least, a healthy ocean and coasts provide us with resources we rely on every day, ranging from food, to medicines, to compounds

Scientific evidence now clearly indicates that the Earth's atmosphere and ocean are warming, and that these changes are foremost due to greenhouse gases obtained from human activities. As temperatures rise, mass coral bleaching events and infectious disease outbreaks are becoming more frequent. Additionally, carbon dioxide absorbed into the ocean from the atmosphere has already begun to reduce freezing rates in reef-building and reef-associated organisms by altering seawater chemistry through decreases in pH. This process is called ocean
With a coastline of over 202,000 km and over a fourth of the world’s freshwater resources, it is no wonder why Canada’s fishing industry is a huge part of its economy.1 Canada exports more than 75% of its fish to over 130 countries worldwide. Many of the 7 million people who reside on the coast depend on the ocean’s resources. In total, Canada’s entire fishing industry is worth around $5 billion a year, being one of the world’s most valuable. However, the coasts have not been treated with respect; overfishing, over consumption, and wasteful practices have deteriorated, not only the industry, but the ecosystems and fish populations. This is a huge global issue; the worldwide collapse of fisheries is projected for 2048.
Given how important coral reefs are, the increasingly disappearance of our coral reef ecosystems will continue to have a detrimental impact on marine biodiversity with in these ecosystems. In addition to the decline of the animal species, job opportunities for many staff members that keep our parks open and healthy for everyone to enjoy, revenue be lost due to the decline in coral reefs. To help ensure this downward spiral in eliminated before it is too late, park officials and scientist conduct continuous research on the effects of ocean acidification and global warming on marine organisms and overall health and longevity of these ecosystems. Ultimately, the goal is to develop ways to intervene before it is to late in hopes that we can reverse the damage already inflicted on our coral reefs and allow these ecosystems to re grow once
Global warming is when the earth's temperature rises because of greenhouse gases, greenhouse gasses in the atmosphere are water vapor, carbon dioxide, methane, nitrous oxide, and the ozone. Climate change is the biggest threat to coral reefs around the world, it has been proven that the global temperature has risen 1.3 degrees since the 19th century. In order for coral reefs to grow, they need limestone and algae. Algae is a nutrient in the water that prevents coral from turning white, but because of the rise in temperature the coral gets stressed and expels its algae which turns the coral white. The reason we have global warming is because we as humans are not picking up after ourselves and we are using fossil fuels that are polluting the air which causes global warming and heats our earth and its
Ocean Acidification is the act of CO2 dissolving into seawater, decreasing its alkalinity and increasing it's hydrogen ion concentration; making organisms sensitive to shifts in the water. Anything from temperature change to toxic waste inflicts some sort of change upon the ocean and the creatures it engulfs. As most people are aware, humans are altering the earth’s climate through producing greenhouse gas that is blanketing our atmosph...
Carbon dioxide disturbs ecosystems candidly, both positively and negatively. On land it increases growth in various trees and plants, an influence occasionally called ‘CO2 fertilisation’. Absorption of CO2 into the oceans triggers ‘ocean acidification’, obstructing shell formation by organisms like corals and affecting coral deterioration or
For decades tourists and local beach goers have been flocking to Southern California in search of an inviting environment to relax and enjoy all the amenities a coastal climate has to offer. Yet despite the beauty and breathtaking atmosphere, many unforeseen factors may alter your perspective in regards to how frequently you visit these beach locations. In its current state many beach destinations surrounding the Orange County, California area are susceptible to urban runoff bringing copious amounts of pollution to the waterfront. As it stands urban runoff is attributing to the decline of water quality in numerous locations like Doheny Beach and Poche Beach, which for several years now have remained present on Heal the Bay’s Top 10 Beach Bummers list. With two of Orange Counties own beaches being present on the Top 10 list, it is now apparent that there is a breakdown in the system in regards to policies responsible for controlling runoff headed to the ocean.
90 percent of the effects of global warming are attributed to rising temperatures and heat. This heat tends to affect our oceans due to the ...
During the 20th century both air and sea temperature has increased and causing several problems. The increase in temperature has caused damages to our eco system. In some countries temperature has increased by a few degrees. In winter, in places where it was cold, now the temperatures has increased and even the sea temperatures have increased, which is melting the Iceberg and destroying the marine life. Scientists projected that if emissions of heat-trapping carbon emission aren’t reduced, average surface temperature could increased 3 to 10 degrees Fahrenheit by the end the century. A good example is that in some Europeans countries the...
Some studies have found “that atmospheric CO2 concentration is approximately 383 parts per million by volume (ppmv), a level not seen in at least 650,000 years, and it is projected to increase by 0.5% per year throughout the 21st century.” (Guinotte) “This is because…the ocean absorbs about a third of fossil fuel emissions, but this amount is likely to increase to 90% in the future.” (Bralower) As a result, “the chemistry of the world's oceans is changing at a rate not seen for 65 million years, with far-reaching implications for marine biodiversity and food security, according to a new United Nations study...” (Knight) “…This change is cause for serious concern [for] many marine organisms…, [because they] may not be able to adapt quickly enough to survive these changes.” (Guinotte)
Pollution comes in many forms. In the ocean we dump a variety of substances, including human wastes, chemicals from fertilizers, oil, and trash such as plastic which all contribute to the growing issue of our ocean pollution. In addition to, our usable waters are finite. More than 97.5 percent of the water on this planet is undrinkable salt water; the remaining 2.5 percent has two-thirds of the usable fresh water locked up in glaciers, snow, and permafrost. Of the one-third of freshwater that is available for human use, 20 percent is used for industrial use. (“Water Pollution”) “In effect, water pollution reduces the volume of water available for use by human and other populations.” (Robin Clarke, Jannet King) Knowing that there are approximately 7.2 billion people and growing on this planet with only 0.83 percent of available for our use wouldn’t you want to do everything possible to help put an end to water pollution?

Climate change and Global Warming are out of control. This means that, no matter what policies, processes or actions are implemented, the Earth as we know it will never be the same again. There is significant evidence to support this hypothesis. The dilemma becomes whether we can limit the damage and adapt to a new status quo or not. Rising sea levels and the damage caused by this phenomenon has irreversible impacts on coastlines worldwide. Damage to sensitive reef systems cannot be fixed. This also has permanent impacts of the ecology not just of those immediate areas but also the ocean as a whole.
The coral reefs of the world are of vast importance because they host 25% of all marine life on the planet. Now that corals have been briefly described, we can see why the effects of climate change damage coral reef systems. Ocean acidification is a result of climate change. Acidification is caused by an increase in carbon dioxide in our oceans and leads to a decrease in the pH levels of seawater. This pH decrease reduces the ability of corals to make their hard skeletons.
Oceans are such so vast that people underestimate the impact their actions —seeming so insignificant— have on them. Humans have by and large taken the oceans for granted; not considering how important a healthy ocean is to our survival. A popular mind-set is that the oceans are a bottomless supply of fish, natural resources, and an infinite waste dump. There are myriad reasons why the oceans should be saved and the most obvious one is marine life. With 71% of the Earth being covered by water, it is obvious that sea creatures are predominant form of life, making up 80% of the species of life on Earth. However, as important as marine life is, that is not the only reason why saving the oceans is crucial. The ocean floor provides natural resources such as, oil, natural gas, petroleum, minerals, medications, and ingredients for foods and products. The economic benefits of the oceans are huge and significant, as well. Fishing and fish products have provided employment to 38 million people and have generated about $124 billion in economic benefits. However, oceans are on the verge of crisis, marine life, natural resources, transportation, the economy, and important ingredients are at risk due to overfishing, pollution, and acidification. Thus, in this essay I will argue that, oceans are not impervious to human activity and threatening the health of the ocean threatens the health of humanity, since oceans key to our survival.
The increase in ocean temperatures are causing the reef to die out; reefs structures don’t have the ability to keep up pace with the ever so changing climate 4. Rigel suggests that coral reefs will eventually die out from the erosion of the warm ocean4. The increase in climate change is leading to ocean acidification. Much of the gases that enter our air from pollution also dissolves into the ocean. With this occurring, corals cannot absorb the calcium they need to maintain their skeletons. The stony skeletons that support coral reefs will dissolve. If nothing is done to stop so much carbon dioxide from going into the atmosphere, this will increase and more and more coral reefs will be destroyed and die
People from all over the world go to beautiful beaches that are filled with water as clear as ice or as beautiful as diamonds. But, what will happen if we do not conserve the appealing sites that draw attraction to the public? Contaminated beaches has become a controversial issue to the public because of the causal problem, the harm to the people and marine animals, the government agencies supporting or opposing pollution, and the industries involved in creating such unlawful decisions. To create and find a solution, we must first find the core to the problem.
