200 Words – Essay on Ocean Acidification for Kids & Students in Very Easy Words
Oceanography is the science that studies the oceans for its physical, chemical, geological and biological aspects. Knowledge of oceans is fundamental, because according to accepted theories, the seas are the center of the origin of life on Earth.
Since their origins, humans have had relationships with the oceans. His first approach to understanding the marine world as a source of food and means of communication was practical and utilitarian.
The most recent research in oceanography has focused on the effects of global climate change on the dynamics of oceans. Now sea water is also becoming acidic due to climate change and human activities. Acidicity is increasing in the sea. Organic acids lower the pH level of water, which increases acidity.
Carbon dioxide emitted from combustion of fossil fuels is also absorbed by the ocean and oceans. The sea and the ocean are losing their biology due to unrest. Climate change, warming of our oceans, rising sea levels and increasing acidification are realities that threaten our food security and the entire life of the Earth.
A large part of the Great Wall of Australia’s coral reef has already suffered significant damage. This is a matter of concern and through debate and movements; It should be discussed worldwide.

The oceans are warming due to rising global temperatures. The acidity of sea water is increasing; Sea creatures such as corals and oysters are increasingly facing difficulties to survive.
71 percent of our Earth’s upper surface, or 362 million square kilometers of land, is always submerged, 90 percent of which is divided between the three oceans – the Atlantic, the Pacific and the Indian. Of all the water available on Earth, 97 percent of it is in the womb of these three oceans. Half of all animals on Earth live in these oceans. From this, it can be estimated how important the oceans have to life and climate on earth.
Coral is a thermometer of the growing disease of the oceans. Richard Spinrod, deputy director general of the US Department of Ocean Research, said that the amount of carbon dioxide gas in our oceans is already tied to their vast waters, which is equivalent to 38 thousand gigas tons – 50 times more than atmospheric carbon dioxide. One GHz is equal to one billion tons.
Spinrod said that even then the oceans are digesting twenty million tons of new carbon dioxide every day. The result is that the carbonic acid formed by the chemical reaction between carbon dioxide and water has made the oceans’ water one-third more acidic than it was a hundred years ago. It is the main cause of death of aquatic organisms like corals, oysters etc.
The hosts of the World Ocean Conference, Indonesia, want seas and oceans to be treated as accumulators of carbon dioxide, like forests. In this way, countries that have long coastlines and wide seawater areas should also get the financial benefit of being helpful in preventing climate change.

According to a study published in the journal ‘Science’, the rising sediment of the oceans may begin to remove the sediments that make up the coral reefs by the end of this century. Based on this study, the team of researchers predicted changes in corals, including several factors including coral formation and current rates of sediment dissolution.
Effect of ocean acidification on coral reefs
The coral reefs are very sensitive to the acidification of the oceans and are extremely threatened by this.
What is a coral reef?
Coral reefs are formed by the formation of calcium carbonate from organisms called coral polyps, as well as carbonate sediments that have been deposited on these organisms for thousands of years. Corals are hard-lime-like primitive creatures. Their biological name is Silentrat Polyps. Within the hard surface of these corals, colored algae are found in the zooxanthella symbiotic relationship. Coral reefs are commonly found in abundance in warm and shallow waters, particularly in the Pacific Ocean, in proximity to many warm or subtropical islands.
Coral reefs are considered to be the center of marine biodiversity of the world and are also called marine rainforests.
The following conditions are helpful for the construction of corals:
- Corals are mainly found in tropical regions, as they require temperatures of 20 ° C – 21 ° C to survive.
- Corals are found at lower depths because there is a lack of sunlight and oxygen at greater depths.
- Clean and non-depressant water is essential for the development of corals because the corals have their faces closed and they die.
- Corals are beneficial for corals because they provide food for corals. Because of this fewer corals are found in closed seas.
Coral reefs are formed by the formation of calcium carbonate from organisms called coral polyps, as well as carbonate sediments that have been deposited on these organisms for thousands of years.
Ocean acidification and challenges for the survival of coral reefs
Marine acidification is defined as a continuous decrease in the pH of seawater. After entering the oceans, carbon dioxide combines with water to form carbonic acid, which increases ocean acidity and lowers the pH of sea water. Oceanic acidification prevents coral organisms from forming their rigid skeletons. It is caused by the oceans absorbing large amounts of man-made carbon dioxide emissions.
When any change in temperature, light or nutrition causes stress on the corals; They expel symbiosis algae Zooxanthellae that inhabit their tissues, causing the coral to turn white. This phenomenon is called coral bleaching. Currently, the coral manufacturing process is also under threat. The incident of coral bleaching was observed in the corals of Lakshadweep in 1998.
The conclusion
Therefore, ocean acidification is not good for the life of coral reefs on Earth, thus it disturbs the balance of life in the ocean because coral reefs are hotspots of marine biodiversity, also known as marine rainforests. To save marine biodiversity, we must work towards the reduction and prevention of ocean acidification.

When carbon dioxide dissolves in sea water, a chemical reaction produces organic acids (H2CO3), increasing the amount of hydrogen ions in the water, increasing the acidity of the ocean. The pH value of water decreases, this process is called oceanic acidification.
In other words, when the basic chemistry of the ocean changes due to a constant decrease in the pH value of the ocean, it is called acid acidification.
Absorption of carbon dioxide by the ocean helps reduce the climate effects of carbon dioxide emissions, but at the same time negatively affects the pH value of the ocean.
Effects of ocean acidification
1: Effect of acidification on the world’s oceans
Estimates of future carbon dioxide levels based on trade as a normal emissions scenario indicate that ocean surface waters may increase acidity levels by about 150 percent by the end of this century.
2: Effect of ocean acidification on marine life
Research suggests that ocean acidification will be a driver for substantial changes in the ocean’s ecosystems in this century. An organism can withstand fluctuations in various pH levels during its lifetime. However, the more acidic environment disturbs some species of marine species such as molluscs, corals and plankton. All of these spheres and skeletons are less dense or weak.
3: Effect of ocean acidification on humans
Changes in marine ecosystems will also have a significant impact on human society, which also depends on the goods and services provided by these ecosystems. The effects of ocean acidification on humans are:
- Food: Mollusks such as loss of muscles from oyster and ocean acidification will cause food insecurity. It is estimated that the loss of mollusks from ocean acidification would be worth more than US $ 100 billion.
- Coastal Conservation: Marine ecosystems such as coral reefs protect shorelines from the devastating action of storm reefs and cyclones, which shelter the only habitable land for many island countries. This protective function of reefs prevents loss of life, property and erosion.
- Carbon Storage and Climate Regulation: The ocean’s ability to absorb CO2 decreases as ocean acidification increases. More acidic oceans are less effective in reducing climate change.
- Ways to prevent ocean acidification
- Carbon dioxide emission reduction: Today, we use fossil fuels for transportation, industry and homes. In recent times, the consumption of renewable energy resources is increasing and huge amount is being invested in it, but we need to do more, as this is the only way to reduce the percentage of CO2 in the atmosphere.
- Ocean management: Since species and ecosystems are already vulnerable and threatened; Protected areas, laws and policies that aim to protect those species should be established and enforced. In this way, the health of marine biodiversity can be improved.
The conclusion
When people become aware of things happening in their environments, they are more likely to respond positively to rules, regulation, and policies that aim to fix things that have been done incorrectly. Individuals need to find and share information from reliable sources. People should invest in education and provide information on these environmental issues, and everyone should be a part of its solution.

71% of the Earth is covered by water, 97% of it is found in the seas and oceans, and only 3% of it is potable, of which 2.4% is deposited in the glaciers of North and South Pole and only 0.6% is water. There is rivers, lakes and ponds. Our ocean acts like a carbon sink that absorbs a quarter of the carbon dioxide generated by humans which causes changes in the basic chemistry of the ocean.
What is ocean acidification?
When carbon dioxide dissolves in sea water, the chemical reaction produces the organic acid H2CO3, which increases the amount of hydrogen ions in the water, increasing the acidity of the ocean and that of sea water. This process is called oceanic acidification. In other words, when the basic chemistry of the ocean changes due to a continuous decrease in the pH value, it is called ocean acidification. Absorption of carbon dioxide by the ocean helps reduce the climate effects of carbon dioxide emissions, but at the same time negatively affects the pH value of the ocean.
Concept and importance of PH scale
The pH scale measures how acidic or basic a substance is. The pH scale ranges from 0 to 14. A pH of 7 is neutral. A pH of less than 7 is acidic. A pH greater than 7 is basic. If the pH value of sea water affects the marine ecosystem and food chain if unnaturally constant. Marine organisms such as corals, echinoderms, crustaceans and molluscs are severely affected.
Due to ocean acidification
Ocean chemistry is constantly changing for the following reasons:
- industrial Revolution
- High concentration of carbon dioxide in sea water
- Fossil fuel use
- Cement manufacturing
- Land use change
- Increased level of carbon dioxide in ocean
- Increase in carbon dioxide in the atmosphere
- High concentrations of hydrogen ions cause chemical reactions.
- Carbonate ions deficiency
- loss of biodiversity
- Change in biogas production technology
- Lack of environmentally friendly laws and regulations
Plastic – as the main source of pollution in oceans
The sea or sea debris is mainly waste thrown by humans that floats or floats in the sea. 80% of marine debris is plastic, a component that has accumulated very rapidly since World War II. Plasticity in the sea can weigh up to million metric tons. Plastic bags and other plastic waste entering the sea pose a threat to the wildlife and fisheries industry. There is a danger of aquatic life getting trapped, breathless and nervous.
Solve the problem
Marine pollution is often difficult to control because pollution crosses international borders, making it difficult to create and enforce regulations. Perhaps the most important strategic policy for reducing marine pollution is education. There are two ways to reduce this overall level of pollution. The first is to either reduce the human population, or find a way to reduce the ecological footprint left by a common human. The second way is for humans to spread less pollution individually. This requires social and political will as well as creating awareness so that more people respect the environment and do less harm to it.
The conclusion
Most anthropogenic pollution enters the ocean. Berne Jansen wrote in his article, “anthropogenic pollution can lead to a decrease in the biodiversity and productivity of marine ecosystems, leading to the depletion and degradation of the resources of human marine foods”. Most people are unaware of the harmful effects of sources of marine pollution and therefore fewer steps can be taken to deal with this situation. In order to make the public aware of all the facts, thorough research is required to give full information of the situation. And then this information should be passed on to the public.
