For example, there was an enormous amount of mercury being dumped in the ocean in the past when people were not aware about the impact the mercury would have to the marine life (Oceanus Magazine). Coastal sediments tend to have levels of mercury that was dumped years ago (ibid). Some mercury in the ocean can come from natural resources such as volcanic eruptions (ibid). On the other hand two-thirds of mercury in the ocean are from human activities (ibid). Also, according to, “How Did Toxic Mercury Get Into Fish?” it states that, “The biggest single source is the burning of fossil fuels, especially coal, which releases 160 tons of mercury a year into the air in the United States alone.
If the planet was to lose all the coral in the world, it would decrease the diversity of the ocean (Casper 184). Plus, the destruction of reefs affect other animals such as reef fish, turtles, and sharks (Casper 185). All this is happening due to global warming. How does global warming affect coral? Global warming has and is still negatively affecting coral due to the rising temperature of the ocean.
From the endless fracking today’s economy is depleting. Our natural resources are at risk every time fracking occurs. Fracking needs to be banned since it is hurting our health and that it drains our natural and limited resources required for us to sustain life. Water is an essential to living and it is a need. Without it we would be dead from the dehydration.
Coral reefs are the beautiful ecosystems that are booming with life but since the acidity has been rising and so has the overall temperature of the ocean the coral has been bleaching and has not been able to grow well or even stay alive(2). The biggest coral reef in the world which is the Great Barrier Reef has been bleaching quickly and now only seven percent of the reef is left unaffected by ocean acidification and climate change(3). Many scientists believe that corals could become fully extinct by the end of the century if we don’t stop or reduce our carbon dioxide and fossil fuel
My first question is if erosion is the biggest problem to ecosystems. I learned that (at least for Hurricane Matthew) erosion was one of the main problems. Another question I have is whether deep ocean creatures are affected by hurricanes. Deep sea creatures that are territorial or are slow-swimmers are guaranteed to be dead but some creatures can swim away. The final question I have is: How are deep sea creatures affected by hurricanes?
Trash, Trash, Everywhere! Text By: Ashley Atkinson Edited By: Hannah Hunter and Jesse Lewis The life of your plastic water bottle can go way further than just the trash can. Our ocean is so polluted by our actions and carelessness that even us humans are being affected, sea animals, and surrounding animals are all being greatly influenced by the polluted waters. Our ocean is extremely polluted with plastics and other trash that humans have put in there. Specifically, 80% of the pollution that’s in the ocean, is because of us.
When a larger animal consumes the hazardous animal, it affects the entire food chain (“What Is Ocean”). Plastic garbage from ships collects in the oceans, where it is eaten by some animals, causing it to choke them or to block their stomachs (Claybourne 38). Littering raises the carbon dioxide levels in the ocean. The carbon dioxide in the trash raises the temperatures of the water, which can lead to coral bleaching. Most of the trash and debris released into the oceans cannot decompose, leaving it floating in the ocean for many years.
Also, the ocean filters the air we breathe, and like said before, supplies 80% of the oxygen we breathe. Pollution causes the ocean not to function properly and oxygen levels can and will diminish. The ocean is also home to medicines that treat heart disease, cancer, and more. The plants or animals that give us these medicines are endangered as long as marine pollution exists. The remedies can be lost causing more people to die because of the lost medicines.
Water bottles, a major controversy in the world of recycling and on the other hand litter. Do you know what happens in our oceans and world when plastic is thrown out or littered? There are many dangerous and harmful effects when this happens. Water bottles are creating a pile of trash in the ocean and on land, and to top it all off we’re the ones who started and created this disaster. I think that plastic water bottles should be banned because it’s pricey and expensive to the economy and to the public, they are lethal to animals, and plastic water bottles are polluting our environment.
It is also ruining the amazing marine biodiversity that South Africa has. Pollution not only comes from industrial sector such as oil companies, but also from littering and sewage. Plastic pollution is one of the types of pollution that effect the marine environment. It is impossible to give an accurate estimation of the amount of plastic that is being polluted into the ocean. However, in 1975 the global fishing fleet alone dumped approximately 135 400 tons of plastic fishing gear and 23 600 tons of synthetic packaging materials
One of the biggest problems on our planet at the moment is the 79 million tons of carbon dioxide being released into our atmosphere every day. According to the European Project on Ocean Acidification, one third of all the Co2 that has been released into our atmosphere has been absorbed by the world 's oceans. Without the immense size of our oceans absorbing all this CO2, our atmosphere would suffer from extreme global warming with devastating effects. However, the downside of our oceans absorbing most of the CO2 is that it threatens the health of our oceans and the animals inside it. It all starts off when the CO2 from the atmosphere is dissolved into the oceans.
This statistic just shows how diverse and enigmatic the ocean is. Despite the ocean’s abundance of marine life and complex ecosystem, it is being destroyed by fisheries. How are these fisheries destroying the ecosystem of the ocean? The answer is overfishing. Overfishing is the depletion of fish stock by too much fishing.
This problem is so detrimental because if not solved, can eliminate species of marine life from different parts of the globe, and can possibly create an ocean in which is not safe for any living being. The harder part of the issue is the one based on the fact that industry growth is at its highest point that we have seen in several million years, and the educated guess that industry will reach a point by 2100 in which a solution for this problem will no longer exist. Us as humans have the ability to solve the issue by limiting the use of greenhouse gases and that will lower the amount of carbon that enters, in the ocean and the atmosphere. Furthermore, this issue is part of a cycle, meaning it will take many years to see any solution. The way that our world is shaped now gives the impression that a solution that will take a ton of effort and time to see results is not worth the change.
