Around 150 years ago, humans started releasing fossil fuels into the atmosphere during the industrial revolution. The ocean takes up a quarter of the gas that surrounds earth by absorbing the CO2 we put in our atmosphere. Scientist thought the ocean was a great resource for getting rid of these CO2 gases in the atmosphere; however, they didn’t know how much these gases where destroying our great ocean. NOVA’s documentary presents, Lethal Seas, a documentary of the destruction of our vast ocean, concentrating on the American northwest coast, Papua New Guinea among the volcanic islands of Milne Bay, and Aurora Australis. The documentary dresses the issue of rising acidity levels in the ocean and its effects.
This becomes a much larger problem when Kolbert talks about the reefs on our world. She states: "This is because out in the real world, reefs are constantly being eaten away at by fish and sea urchins and burrowing worms" (Kolbert). What Kolbert means by this is as the PH levels in our oceans drop, the rate at which reefs grow will decrease. With the decrease in production rates, the reefs will not be able to keep up with the fish and other organisms that break them. World wonders will slowly begin to erode away to extinction and
The carbon dioxide levels have risen over the last 10,000 years. CO2 is thought to be the greenhouse gas that causes climate change and global warming. It possibly went up due to the increase in the population. Since we breathe in oxygen and exhale CO2. Everything is putting CO2 back into the environment but, at high rates.
In today’s world there are many contributing factors to the pollution of the oceans. Many people may think that because they don’t live close to the ocean that they are not the root cause for the pollution that is occurring. Well they would be wrong in every sense of the word. It doesn’t matter where you live whether it be close or far from the ocean you are having an impact on the ocean. A few weeks back I partook in a service learning project at the Sodalis Nature Park and I was taught all about how one invasive plant species can have a negative impact on the ocean.
The ocean covers 70 percent of the Earth. The ocean helps absorb carbon dioxide from the atmosphere and provides 50 percent of the oxygen in the atmosphere. Ocean acidification is the harmful consequences of excess carbon dioxide in the atmosphere. Ocean acidification has been rapidly increasing do to the excess amounts of carbon dioxide in the atmosphere produced by humans. Humans impact ocean acidification by increasing carbon emissions, creating waste, and loss of biodiversity.
The topic of this research paper will cover over Ocean Acidification and the effects on marine ecosystems. Ocean acidification is the decrease in pH levels of the Earth 's oceans, due to overbearing carbon dioxide being brought by the atmosphere. The carbon dioxide is drawn by seawater, where the chemical reactions take place, which minimize the pH levels in the ocean, the carbonate levels and the important calcium carbonate which these sea creatures need. When carbon dioxide disperses in this ocean, it causes the levels of acidity to rise towards the the surface, where most shell growth in marine animals have been stopped and has created the cause of reproductive disorders in multiple fish. Part of the problem with ocean acidification is human activity.
A. There are other ways also that affects the ocean through global warming. Plenty of things that are happening to the ocean are associated to global warming. One important thing is warm water which is caused from global warming and it is harming and killing algae in the
Name: Ng Xin Yi ID number: I14005408 Tittle: Acid precipitation and ocean acidification threaten the environment. Introduction Ocean have maintained stable pH level ten million years ago. However, the pH value of ocean waters has drop year by year since the beginning of industry evolution. The impact on beginning of industry evolution lead to releasing billion tons of carbon dioxide gas and some other greenhouse gases into Earth 's atmosphere. The release of excessive carbon dioxide gas has been absorb over time by the ocean.
When the planet warms from all of the greenhouse gases and pollutants being released into the air, it warms the oceans up, too. If oceans warm, it causes coral bleaching, which if severe kills the coral. We need to save these beautiful ecosystems for the species that inhabit it, as well for us. State of the Issue:
A pressing social problem prevalent in the world today is the destruction of marine habitats which leads to the loss of food for humans. I am going to discuss the many causes of the deterioration of the marine habitats such as development, chemical run off into water supplies, bottom trawling and dams. “Habitat loss in these areas have far-reaching impacts on the entire ocean 's biodiversity” says National Geographic (2014). Our population is growing at an exponential rate; according to National Geographic (2018) they predicted that by 2050 (which is only 32 years away) that the population will grow by 2 billion more people.
However, in this era of rapid industrialisation and globalisation, the pollution of the global ocean has become the major worldwide issue of discussion. Even a former French naval officer and
As demand for metals and other materials grow in economy, countries turn to the ocean for collecting these materials that may occur more readily in the ocean floor. As informed by conserve-energy-future.com, the deepest parts of the ocean are being affected the worst by the mining; and acidity is increased due to the materials polluting the water: “For example, copper is a major source of pollutant in the ocean and can interfere with the life cycles of numerous marine organisms and life.”. They also state that as the acidity increases, corrosion of man-made objects is inevitable, leading to more pollution due to degrading material and increased oil spills. This then leaves another overcast of deadly substances to hinder the lives of creatures that must endure the circumstances placed by human
Arguably the most significant thing humans have done to cause climate change is the drastic increase in CO2. As a result of human activities, carbon dioxide, methane, nitrous oxide, and the halocarbons (a group of gases containing fluorine, chlorine, and bromine) build up in the atmosphere over time, as well as the natural sources of CO2, like vegetation. The concentration ofCO2 has went from 280 to more than 380 parts per million in just two hundred years. Still currently rising, the burning of fossil fuels by humans will continue to cause global warming and climate
“ Natural gas industry has been identified as a major source of water pollution “ ( source 1 ). This quote from source 1 explains how out of all the ways of polluting the oceans, oil is always one of the worst. “ 8 million metric tons of plastic trash enters the sea from land every year “ ( source 4 ). This quote from source number 4 explains how every year tons and tons of plastic from land, gets into the oceans and continues to pollute. Garbage is polluting the oceans so much that the water is getting so bad, people are getting ill from drinking
People are not only affected by the ocean, the ocean is also affected greatly by people. Firstly, human development, such as the construction of a river or a dam, can change the ocean geologically. The reason behind this is that the Earth’s ocean is all connected with multiple basins. Secondly, human activities, such as diving, can affect the ocean through the unnatural invasion of the marine environment without proper knowledge of what to do. Thirdly, the ocean and its inhabitants are greatly affected by marine pollution.
