Land Pollution: Causes, Effects, and its Prevention

elonjeevan

Our environment is deteriorating day by day. Air and water pollution comes to the forefront of our minds whenever we talk about pollution The main cause of it is human itself. Which gives birth to different kinds of environment pollution and one of those kinds is land pollution. 

Before proceeding let's understand the basics of what pollution exactly is? Pollution is the introduction of harmful substances into the environment. These harmful substances are called pollutants. Pollutants damage the quality of water, air and land. In this article, we will focus primarily on land pollution its causes, effects and solutions. 


Land Pollution: Causes, Effects, and its Prevention


What is Land pollution ?

Land pollution, means destruction degradation of the Earth’s surface and soil, directly or indirectly, because of human activities. 

It is a global issue which is the need of the hour to fix immediately. The unwanted materials contaminate the quality of our land.

we should  implement the preventive measures to control land pollution, Before that you must be aware of what causes land pollution and how it affects the environment.


Causes of Land Pollution

There are various causes which contribute to this pollution such as agricultural waste, household waste,  industrial waste etc. The most common ones are: 


  • Mining activities

Mining is the extraction of minerals and other geological materials from the ground, which are then used for a wide range of purposes, such as generating electricity, producing gasoline for automobiles etc. 

Mining activities sometimes require harmful chemicals to extract natural resources from the earth's surface. These chemicals can have adverse effects on the soil which can eventually disrupt the life of plants and animals.


  • Deforestation

Deforestation is one of the most common causes of land pollution. Forest lands are sometimes losing trees due to natural causes like forest fires but most of the time due to man-made causes.

We have deforested for various development reasons, but the sad truth is that "once the land is turned into barren land, it will not be able to regain its fertile power."

Land conversion, that is the change or modification of real estate to make it usable for a particular purpose, is another major factor. This gives the ground too much barrier.


  • Chemicals from agricultural activities

Due to the increasing population worldwide, The use of pesticides & fertilizers has been increased a lot these days to improve productivity of the crops.
The harmful chemicals used in the form of fertilizers & pesticides ultimately contaminate the land when mixed with the soil.


  • Landfills

Landfills  are one of the leading causes of land pollution. Every year each household produces tonnes of garbage. Garbage like paper, cloth, wood, aluminum, plastic is collected and sent to the local recycling unit. Most of the items that can not be recycled become a part of the landfills that cause land pollution.

  • Construction Activities.

Every day there is new construction work going on to fulfill needs of the people.  construction work has resulted in huge waste articles like wood, metal, bricks, plastic etc. 
If we do not dispose of these by-products properly after completion of the work, then it may cause harm to the land.

  • Disposal of Nuclear waste.

Nuclear waste is a dangerous way to pollute the earth. Residual radioactive substances contain harmful and toxic chemicals that can affect human health. They are thrown under the ground to avoid any casualty. This way of disposal causes serious consequences for years by contaminating the land.

  • Sewage Disposal

Improper Sewage disposal is one of the major causes of land pollution. It should be treated in a professional way to protect the soil and more importantly, groundwater which is an essential source of water for us.
If sewage is not treated correctly, it produces harmful toxins that seep into the ground, causing land pollution.

  • Littering

Littering is also another major cause of land pollution. It is a common problem, no matter it is an urban or a rural region. People just throw their garbage on the land without caring about the harmful effects on the environment. Garbage contains  plastic, cigarette butts etc. 

Effects of Land Pollution

Land pollution affects all the living organisms whether it is plant, animals, or human beings. The main effects of land pollution are following-


  • Soil Pollution

Soil pollution is another form of land pollution. It is mainly caused by deforestation, overgrazing and other agricultural activities like the use of pesticides or fertilizers. If it continues for many years, then the topsoil will lose its fertility. 

 The regeneration process of topsoil takes at least 500 years for 2.5 centimetres . The United State of America  loses soil at the rate 17 times higher than it usually takes to generate new topsoil.


  • Drinking Water Problem

Drinking water is highly affected by land pollution. According to UNO's Report  2.5 billion people have access to better drinking water, but still 663 million people are deprived. Every day about 1,000 children die of diarrhea which is caused by water pollution. 


  • Groundwater Problems

When harmful substances from industrial processes, chemicals are improperly disposed of on the land it gradually seep in the ground. which  affect the purity of the groundwater.

These toxins contaminate the groundwater that ultimately affects human health.  Even  animals and plants also have to suffer a lot due to groundwater contamination.


  • Climate change

Land pollution is indirectly affect the climatic conditions of the globe. it is responsible for the loss of ecosystem. 

land pollution decreases the fertility rate of topsoil that means less plants will grown in future. Trees plays an important role to cool down the environment because they absorb carbon dioxide. But less forest lead to global warming which causes climate change. 

  • Causes air pollution

One of the leading causes of air pollution is land pollution. A vast number of  burning of garbage emits various toxic gases in the atmosphere. These gases are responsible for the deterioration of the quality of air. 

When we breathe in such unhealthy air, it causes various health issues such as respiratory problems, lung problems, and asthma etc. Due to air pollution, 70 lac people die each year. 


  • Habitat Shifting

When soil erosion and deforestation are in progress, animals are forced to move from their natural habitat to find food & shelter. 
The change is too distressful for some animals, and this even leads to loss of their life. As a result, some species are posed with a greater risk of extinction.



  • Impacts on wildlife

Wildlife plays an important role in our ecosystem. The wild animals  are equally paying for the land pollution caused mainly by human sources. They face a serious threat with regard to the 'loss of habitat' and natural environment. 
Due to deforestation several species are  pushed to the verge of extinction. forests are home for wild animals. 


  • Impacts on plants

Plants are also affected by land pollution. Fertility of topsoil is very important for the growth of plants. The harmful chemicals alter the soil property that creates a big problem for the vegetation of the plant.

The poor-quality of soil causes the extinction of many plant species.


How to prevent land pollution


  • Follow 3 R's

We should aware people of the concept of 3R's that means Reduce, Recycle and Reuse. 3Rs is important to minimize the amount of waste in the landfill.

  • Reduce plastic

Plastic has become a significant issue for the whole world. It is a big environmental issue that not only pollute the land but also causes water pollution and Air pollution. 


  • Reforestation

Reforestation means replanting an area with trees. This can be needed for areas that have experienced Forest fires or where trees had been chopped down and milled. 
This process helps to bind the soil, which helps to protect it from land pollution, prevents soil erosion and flooding.


  • Use less Pesticides and fertilizers

 Reduce the use of fertilizers and pesticides in agricultural activities. it helps a lot to prevent land pollution. 

  • Avoid single use packaging

We should switch to reusable cloth bag for groceries instead of plastic shopping bags to reduce single use plastic waste. Say 'no to single use plastic'  is a small and easy initiative to reduce land pollution. 

  • Raise awareness

 Raising awareness always makes a difference to reduce land pollution. You can share information or discuss the causes, effects, and solutions to mitigate land pollution.

  • By educating people

Education is key to prevent the land pollution. We have to show people the adverse effects of land pollution and the way to reduce them. Convince others to significant contribution to save our environment. Because someone well said

"LITTLE STEPS BRING HUGE CHANGE"

Conclusion 

As human beings are majorly responsible for causing land pollution, hence it is our responsibility to reduce this problem. 

As a good citizen it is one's duty to share information with your friends to save our planet.

5). Fix Leaks of taps and showers-


It is estimated that unknown leaks in your  taps, pipes, and toilets  can waste up to 3,000 gallons (11,000 L) of water a year. By  fixing these leaks you can save a lot of water.




How to Save Water In Kitchen 


1). Clean vegetables and fruits in a pan - 


When you need to clean fruits and vegetables with water, fill a pan of water to wash them instead of letting the tap run. By doing this, we can save a lot of water. you can reuse this water for watering the plants.



2). Reuse the RO waste water-


Store the waste water of RO in some tank or bucket and re-use for other household works like washing utensils, floor mopping, washing your car, watering your plants, etc.



3). Use automatic dishwasher for full loads only-


Always remember to load your dishwasher to its full capacity. This will avoid multiple running cycles of the dishwasher. By doing this you can save a lot of water.

   


4). Fill up your sink with water to rinse the dishes.



 Don’t leave the water running for rinsing when you are washing dishes by hand. Fill up your sink with water or bucket for rinsing the dishes. This will help to minimize the water wastage. 



How to Save Water In outdoors ?



1). Use a broom to clean Verandah or Backyard instead of pipe-


If you are cleaning your backyard, use a broom to remove dry matter. If the area still needs additional cleaning, use a bucket of water. Using a water pipe wastes hundreds and hundreds of gallons of water.



2). Use a rainwater tank to store rainwater- 


A rainwater tank is one of the best ways to save water. You can use collected water from  rain in many household works.

Why deforestation In Amazon rainforest Surges during Pandemic ?

elonjeevan


As the Coronavirus epidemic draws global attention, there is a significant increase in deforestation in the Amazon rainforest in 2020, which is a matter of great concern.

Deforestation in Brazil’s Amazon rainforest rose sharply in last month April 2020. Destruction in Amazon forest increased 64 percent in April 2020, compared with the same month in 2019, according to preliminary satellite data from space research agency INPE.



Deforestation reaches highest level in a decade in the Brazilian Amazon

According to the INPE data, in the first four months that means from January to April of this year, Amazon deforestation was up 55 percent from a year ago to 1,202 square kilometers (464 square miles). 




How is the coronavirus epidemic responsible for increasing deforestation?


The outbreak of the new coronavirus has led to sophisticated efforts to combat deforestation, with environmental enforcement agency Obama sending fewer agents to farms due to health risks.

The coronavirus epidemic is only complicating things in the Amazon region.
Brazil, which accounts for more than 60 percent of the Amazon, is the epicenter of the epidemic in Latin America, with about 10,000 deaths so far.


Environmentalists say the government is paying less attention to deforestation due to the coronavirus.


New question arises that how Brazil is protecting its world's biggest rain forest?



The Amazon is the world’s largest tropical rain forest, and scientists say its preservation is vital to stop global warming because it absorbs vast amount of greenhouse gases.

Destruction of the Amazon surged to an 11-year high last year due to massive fire and continues to surge in 2020, which environmentalists blame on the policies of  President Jair Bolsonaro who has emboldened illegal loggers, ranchers and miners.

Last year, in Bolsonaro's first year in office,  soared 85% in the Amazon rainforest deforestation, to 10,123 square kilometers of forest.

The destruction was increased by massive fire across the Amazon forest from May to October in last year, in addition to illegal logging, mining and farming on protected lands. This trend in 2020 is still matter of concern.



President of Brazil has called for more farming and mining in protected areas of the forest, saying it is the only way to lift the region out of poverty.


Causes of  deforestation in the amazon rainforest


Illegal logging, mining and farming on protected lands is the main cause of amazon forest deforestation.



Illegal logging in amazon rainforest
Illegal logging in amazon rainforest 


Cattle ranching is the another leading cause of deforestation in the Amazon rainforest.


WWF estimates that 27% – more than a quarter – of the Amazon  will be without trees by 2030 if the current rate of amazon rainforest deforestation continues.



Effects of deforestation in amazon rainforest 


Wildlife habitat destruction due to deforestation will cause more deadly pandemics like coronavirus. Because when you cut down trees and remove the forest, you eliminate the natural environment of many species.

Millions of plant and animal species currently face extinction because of habitat loss.

34 million indigenous people live in the jungles of the Amazon and depend on its resources. Deforestation in the Amazon can be a major problem for these people.





Ways to stop deforestation in the Amazon



Deforestation in the Amazon is no longer an issue for individual countries to deal with alone. It requires an integrated policies and concrete actions to deal with this problem. 

Brazil government has to design and implement “zero net deforestation” plans, create awareness of the issues about deforestation, and recognize indigenous peoples and local communities’ rights.

President of Brazil Bolsonaro already authorized the deployment of armed forces to deter illegal loggers and combat deforestation and forest fires in the region. This measure may help in the short term to stop deforestation but is not a lasting solution.


Conclusion



The Amazon Rain Forest in Brazil is the largest tropical run forest in the world. It is also called the planet's lung because its vast forest releases oxygen and stores carbon dioxide (CO2). 

More than 20% of the world's oxygen is produced in the Amazon rainforest. Therefore, it is a matter of great concern that Amazon Forest is being destroyed day by day. we should think about this problem deeply.

Water Pollution Essay Every Student Should Know About It

elonjeevan
Water is a precious thing. without water We can not imagine our life. Water is very essential for human beings to live. We use water for drinking, bathing, irrigation and sanitation. We need clean water for these tasks.


Water Pollution Essay for students 3-6
Water Pollution Essay for students 3-6


But these days water has become polluted.  Many types of dirty elements have mixed in water.  Dirt, plastic, rotten-throat substances, disinfectants etc. have reduced the quality of water drastically.

Dirty water contains harmful germs that harm our health and also the entire Ecosystem. So, water pollution is becoming a major problem on the earth.

In this water pollution essay we will discuss the causes and effects of water pollution and how we can prevent it from happening.

We wrote this water pollution essay in easy wording. so that students between the ages of 6-15 can easily understand it.

Every child should know about water pollution because children are the future of our country. Our little efforts bring a huge change.


Introduction: what is water pollution?


 Water pollution results when pollutants are introduced into the water bodies such as lakes, rivers, oceans, and groundwater. For instance, releasing treated wastewater into natural water bodies can cause degradation of aquatic ecosystems.

Water is an integral basis of human life. As we all know that all human beings and animals depend on water.

The contaminated waste coming out of the industries in the natural water sources is threatening human life. Due to increased industrialization  the problem of water pollution is being assumed day after day. Therefore, there is a need to look into this problem.



Causes of water pollution


Water pollution has many causes, The major cause of water pollution is human itself. We pollute water bodies through various activities such as, agricultural activities, industrial waste etc.In this water pollution essay we will cover major causes that are as-




Sources that cause water pollution can be divided into two categories:

1). Direct Sources
2). Indirect Sources


Direct Sources:-  Those sources are called direct Sources of Water Pollution which directly enter into the water and contaminate it. For instance,disposal of waste, plastic, the urban sewage, industrial waste, and Oil Spills in oceans, etc. 


Plastic, industrial waste and oil spill are direct sources of water pollution
Plastic, industrial waste and oil spill are direct sources of water pollution 


These are a major cause of water Pollution all across the world. Plastic is very dangerous for marine species. 


Indirect Sources:-  Indirect Sources can be chemical dump, fertilizers, pesticides, septic tanks, etc.contaminate the water indirectly. When these harmful chemicals are used on plants in the field,  the rain washes these chemicals and mixes them with soil. 


Pesticides, insecticides and other chemicals are indirect sources of water pollution
Pesticides, insecticides and other chemicals are indirect sources of water pollution 

Through soil, it reaches down to rivers, lakes and other water bodies, and that pollutes water.


Harmful Effects of Water Pollution?


Water pollution has adverse effects on human health and the environment. Drinking especially polluted water has led to many frightening diseases. Many infants end their lives with diseases like diarrhea, cholera. Its root cause is polluted drinking water. 

We should consider our responsibility for this and should be aware of various diseases like diarrhea, malaria, malaria and other diseases that result from impure water. 

There are much more harmful effects of water pollution which are as -

  • Effects of water pollution on human health 


Diseases:- when we drink polluted water. it has many harmful effects on our health. It can cause typhoid, hepatitis, cholera, and various other diseases. 80 percent of the world's diseases are caused by impure water. Many Children had lost their lives in developing countries due to the lack of potable water. 


  • Water pollution affects the food chain



Water pollution is highly affected the food chain. Disruption in food chains happens when toxins, pollutants and plastic  in the water are consumed by marine animals such as fish, shellfish etc. These pollutants get transferred when big animals eat small aquatic animals. Finally, these pollutants enter the human body when we consume fish in our meal. 


  • A Problem Of Eutrophication



 Various chemicals when entered into water bodies like ponds, lakes, rivers etc pollute the water. When these chemicals dissolve with water, it encourages the growth of algae. Further this algae covers the upper surface of the water bodies. Due to increase in the growth of algae causes the level of oxygen decreases in the water that affects the ecosystem of underwater.

  • Water Pollution is a threat for biodiversity.


Our ecosystem requires a balance for a healthy environment to live peacefully. Water pollution is a big environmental problem. It affects the entire balance of our ecosystem.
When the level of pollutants increased in the water bodies due to water pollution. Unfortunately, then the Marine animals like fishes,turtles die.


Solutions : How Can We Control and Prevent Water Pollution?


We can reduce the effects of water pollution by following some preventive measures. which are as follows-

Your most important step should be to save water. Wastage of Water is one of the major environmental issues worldwide. you can start saving water by making small changes in our daily life.
For Instance- Use a bucket while bathing instead of shower.
                        Turn off the taps while brushing your teeth


  • Use less pesticides, fertilizers and chemicals. 



You should try to use less pesticides and fertilizers for agricultural purposes to control water pollution. In the end, the chemical emit from these pesticides and fertilizers goes into water bodies causing water pollution.




The waste released from huge factories, industries should be disposed of in a proper way. Improper sewage disposal is also one of them. you should not leave your trash in the open around the beach. 

  • Use Eco-friendly products



You can use Eco-friendly households to minimize water pollution. such as bamboo toothbrushes. Using Eco-friendly products is a very good initiative to control water pollution. 


Long Story in short (Conclusion)


 Our life majorly depends on water. We have a fundamental right to drink potable water. but we all are helpless to drink polluted water because of our own habits. We can control this problem with our little efforts.

You can take initiative to take some helpful steps to reduce water pollution, such as by using less pesticides, using Eco-friendly detergents etc. You can also work in a group at your school to aware more people about water pollution, its causes, effects, and preventive measures.

I hope you like this essay (essay on water pollution) please share it with your friends. so that everyone can help to control water pollution. 

Thank you!!

What are major Ocean Environmental Problems and solutions ?

elonjeevan

Ocean environmental pollution is a major threat to the ocean ecosystem and marine life. The oceans cover about 70 percent of the earth's surface. Despite these vast areas, the world's oceans are in grave danger.
Human activities are a major threat to the health of the world's oceans. About 80% of marine pollution comes from land-based activities (trash and debris). From coral bleach to rising sea levels, marine environments are changing rapidly.

Marine Debris is a major problem ( flickr)
Marine Debris is a major problem 



Plastic and global warming greatly affect the marine animals. Around 8 million tons of garbage are dumped into the ocean every day. Due to Global warming the temperature of oceans increases and it is threatening many  marine species that cannot cope with higher temperatures. Overfishing has also become a serious problem for all over the world.

In this article we will discuss the major ocean environmental problems one by one in detail and try to find their solutions.

1). Plastic Pollution


Plastic pollution not only threatens human health, but is also harmful for Marine Species. Over 300 million tons of plastic are produced every year, half of which is used to make single-use items such as shopping bags, Disposal cups and plates, straws etc.

About eight million tons of plastic end up in oceans every year, and make up 80 percent of all marine debris from  surface water to deep-sea sediments.


via GIPHY

As we know Plastic is a Non-Biodegradeable substance. In the ocean it is divided into small pieces called microplastic. Marine species ingest or are entangled by plastic waste, which causes severe injuries and deaths. so plastic is one of the major reasons for the extinction of marine species. (IUCN)


Have you Read - 

How does plastic harm the environment
Facts About Plastic Pollution (2019), Which you have to know


2). Overpopulation


The current population of the Earth is over 7.6 billion people and growing day by day. It could reach Eight billion by 2025. As the human population grows, the rate of extinction of species is increasing. because human beings are doing all illegal activities to fulfill their needs. such as, Over fishing, hunting and Poaching.

One more thing, A vast amount of the discarded waste of consumers also finds its way to the oceans which Causes deaths of marine species.

The demand of an unsustainable human population for large-scale terrestrial food production also affects the oceans in devastating ways. Marine fish provide 15% of all animal protein consumed by humans. Under this pressure - 15% of total Population (and growing every year) global fisheries are collapsing.

Lastly, overpopulation is a major threat for oceans and marine species.

3). Ocean temperature rise


Climate change is the main cause of rise in ocean temperature. Scientific reports  indicate that the Earth's atmosphere and ocean are warming day by day, and these changes are mainly due to greenhouse gases derived from human activities.

The Rise in ocean temperature is the cause of the killing of coral reefs across the planet. Coral reefs are home to the widest diversity of fish and plant species in the ocean, but rise in ocean temperature due to Climate change causing them stress.


via GIPHY


4). Ocean Acidification



Ocean acidification refers to a reduction in the pH of the ocean which is caused mainly by ingestion of carbon dioxide (CO2) from the atmosphere.
 The concentration of carbon dioxide (CO2) in the atmosphere is increased due to the burning of fossil fuels, and other agricultural activities.
Oceans absorb carbon dioxide from the environment to maintain heat on the earth's surface.  but the excess amount of heat increases the ocean temperature. which lowers the pH, making oceans more acidic.

Ocean water is less acidic than fresh water. Normal ph of ocean water is 8.2 . But as the ocean absorbs more and more carbon dioxide(CO2) from the atmosphere, it becomes more acidic. Which is very harmful for marine species such as coral reefs, Algae and plankton etc, that  disturb the whole food chain.

The alkalinity of the oceans is very important in maintaining a balance needed for marine animals. If the ocean water is too acidic, the animals may not be able to make strong shells. ( Climatekids )



5). Unsustainable Aquaculture


Vigorous aquaculture at sea advocates the proliferation of pollutants in ocean water.

The production of marine fish, crustaceans and bivalves involves the use of antibiotics, pesticides and other chemicals.  one of them nitrogen-based wastes can negatively affect the marine ecosystem.


6). Invasive species in the ocean


Invasive species can lead to the extinction of native marine species, destroy biodiversity, and permanently alter habitats through both direct and indirect effects. Invasive species may negatively affect native marine species due to direct interactions like Predation and competition. For example, they can spread diseases in native species.This can cause native species to be  vulnerable.

Without  check and balances in invasive's new range, their population can increase dramatically in a short period of time. This growth may reduce habitat quality, lower biodiversity, and eventually impact fishery resources and protected marine species. (Invasive and Exotic Marine Species)


7).  High Levels of Mercury 


Excess mercury causes severe illness in humans and marine life. High levels of mercury can cause serious diseases. 
Mercury enters the environment through many routes and one of them enters the human body is through the ingestion of fish. As the temperature of the ocean rises the level of mercury in fish also increases. 
 As a result, the consumption of  the black scabbard fish and tuna should be regulated. 


8). Ocean habitat destruction



When marine environment or the ecological setup is unable to support marine species is called marine habitat loss or destruction. 

 Main causes of habitat destruction are climate change, land pollution, plastic pollution, unsustainable fishing, shipping impact etc. 

Habitat loss causes less oxygen construction in ocean water which is not able to support aquatic life. Animals such as whale, sharks depend on other aquatic ones for food. In the last marine habitat loss disturbs the food chain. 





9). Overfishing



Over fishing has some serious effects on our oceans. Overfishing is not only wipe out fish species but also responsible for the extinction of those species which directly or indirectly depend upon fishes for food.


10). Oil Spilling


Oil spills can be catastrophic to local marine species such as fish, birds and others. Oil spills make up about 12 percent of the oil that enters into the ocean. The other 88 percent come from shipping travel, drains and dumping.


As we all know that Oil cannot dissolve in water and forms a thick layer in the water. This sludge layer suffocates fish, gets caught in the feathers of marine birds. another major threat is that this oilly layer  blocks light from photosynthetic aquatic plants.


Frequently Asked Questions (FAQ)


1). What does coral bleaching mean?

When ocean water is too warm, corals will expel the algae (zooxanthellae) living in their tissues causing the coral to turn completely white. This process is called coral bleaching.


2). What is the most toxic form of mercury?


Methylmercury  [CH3Hg] is the most toxic form. It affects the immune system, enzyme systems, alters genetic and damages the nervous system.


Ocean Pollution Solutions


  1.  We must reduce single-use plastic items, such as straws, plastic bags, plastic cups, cutlery etc. 
  2.  Proper waste management is must to save the oceans. As a solution an international aid programme should be established to develop waste management and recycling infrastructure. 
  3.  Goverenment must increase funds for clean up to solve the plastic problem.
  4.  Avoid Products Containing Microbeads (Tiny plastic particles). Microbeads are found in face scrubs, toothpastes, and bodywashes, and they readily enter our oceans through our sewerage systems, and affect marine species. 
  5.  Support those Organizations which are Addressing Plastic Pollution such as  Oceanic Society, Plastic Pollution Coalition, 5 Gyres, Plastic Soup Foundation, and others. 
  6. Reduce Carbon Emissions to stop ocean acidification which harm marine life.
  7. Do not buy jewelry or other items made from coral, tortoise shells, or other marine species. 
  8. Donate as much as possible to an organization that protects the ocean. such as Blue Ocean Society, Greenpeace, Ocean Conservancy etc. 

Conclusion


Oceans are boon for us. Because they absorb carbon dioxide from the environment which is important for the existence of human being on earth. so, we should take care of our oceans by changing our daily habits.
