¡¡¡¡The ocean and we are a whole, first of all, the ocean itself has great handling of pollutants, dilution, diffusion, oxidation, reduction and degradation of purification ability.

¡¡¡¡But the capacity is not unlimited, when toxic and harmful substances accepted by the local waters more than its own self-purification ability, it will cause pollution of the waters. In addition the ocean while contains many resources, but the regeneration of marine resources is the need of time, if the development of marine resources we uncontrolled and not pay attention to the protection of these resources, so there is always used in the light of day. So the protection of the marine is extremely important.

¡¡¡¡here are many kinds of animals in the world,but not only the humans.we live in the same world,and we should be friends.as everybody knows,the humans are the rulers of the world today,so we should protect our friends--the animals!

¡¡¡¡but how to protect them?as first,i think we must stop killing the rare birds and animals,especially the young ones.the second,we have to protect the environment,to make the sky blue,to make the grass green,to give the animals a comfortable space to live.

¡¡¡¡There are still many problems of environmental protection in recent years. One of the most serious problems is the serious pollution of air, water and soil. the polluted air does great harm to people¡¯s health. The polluted water causes diseases and death. What is more, vegetation had been greatly reduced with the rapid growth of modern cities. To protect the environment, governments of many countries have done a lot. Legislative steps have been introduced to control air pollution, to protect the forest and sea resources.

¡¡¡¡and to stop any environmental pollution. Therefore, governments are playing the most important role in the environmental protection today.

¡¡¡¡In my opinion, to protect environment, the government must take even more concrete measures. First, it should let people fully realize the importance of environmental protection through education. Second, much more efforts should be made to put the population planning policy into practice, because more people means more people means more pollution. Finally, those who destroy the environment intentionally should be severely punished. We should let them know that destroying environment means destroying mankind themselves.

¡¡¡¡Sea pollution is becoming an increasing problem for our planet and we have a responsibility to reduce sea pollution.

¡¡¡¡I need to describe the problem. Our ship currently dumps all its rubbish into the sea.It's easy to result in huge endanger. First of all, Non-organic substances such as plastic bags kill fish and whales. Because fish get trapped and whales cannot digest them. Secondly some rubbish is inherently toxic.

¡¡¡¡I can suggest some solutions. First and foremost we can create a better system of disposing of rubbish for instance. We ought to store rubbish. Next, we are supposed to make ships environmentally and friendly. A case in point is that we should stop providing plastic bags.

¡¡¡¡We must act now before it is too late!

¡¡¡¡Marine biological environment is a complex system including sea water, sea water, soluble matter and suspended matter, seabed sediments and marine organisms. The rich biological resources, mineral resources, chemical resources and power resources in the sea are indispensable human resources treasure houses, which are closely related to the survival and development of mankind.

¡¡¡¡At present, the main objective of marine conservation is to protect marine biological resources so that they can not be exhausted for sustainable use by mankind. In particular, priority should be given to the conservation of marine animals that are valuable and endangered. According to the UN investigation, due to overfishing, mangrove accidental killing of non target to allow the killing of marine organisms, the coastal engineering construction, deforestation, pollution of the marine environment in general, at least 25 of the world's most valuable fisheries resources consumed, whales, sea turtles, manatees and many other marine animal faces the danger of extinction. It is expected that with the expansion of marine development, it is possible to cause more damage to marine biological resources.

¡¡¡¡Marine protection task should first stop on the marine biological resources excessive use, secondly to protect the marine biological habitat or habitat, especially their migration, spawning, feeding, avoid Huahai coastline, beaches, estuaries, coral reefs, to prevent heavy metals, pesticides, oil, organic produce and eutrophication. Nutrients such as marine pollution. Maintain the ability of regeneration of marine biological resources and the natural purification ability of the sea water, maintain the marine ecological balance, and ensure the sustainable development and utilization of the marine.

¡¡¡¡The earth is the home of all living things and the real mother of human beings.Earth gave birth to us, but what about us?Excessive exhaust emissions, deforestation, the earth's greenhouse effect, the destruction of the ozone layer, the extreme lack of water resources on earth...Our mother has lost her old smile.

¡¡¡¡Seventy percent of the earth's area is ocean.The sea has nurtured our ancestors and helped the development of a generation of human civilizations.But we are ungrateful, turning the sea into a waste room of the earth and a bloody hunting ground.

¡¡¡¡Millions of years ago, the sea was a peaceful, joyous place, maintaining a natural ecological balance, and thousands of years later, human beings entered the ocean and broke the original calm.People have discovered that the resources and food are so abundant that they have begun to indiscriminately kill Marine life and oil and other resources.However, they did not find that they had broken the ecological level.To date, there are more than 10 billion fish and dolphins killed on average every year, and this amazing math has been going on for hundreds of thousands of years.However, people finally found out how cruel their behavior was, so some people gave up hunting, but the blood in the ocean didn't last, and the crazy emissions started again.With the development of industry, many waste gases and liquids have been discharged into rivers and into the oceans through rivers, causing a sharp decline in the Marine environment.The sea creatures died a lot, and the rest were forced to flee to the depths.The oceans are running out of support, and human bad behavior is continuing...

¡¡¡¡The earth, the ocean is our mother, in order for our great mother to return to the calm and happiness of the past, cry for: protect the earth, cherish the environment, do not destroy their home again!

¡¡¡¡Boundless sea to look forward to, give people the beauty, give a person warm motherly love.

¡¡¡¡The sea is like a poem; it jumps; like a picture, rich in meaning; and like a symphony, vast and mighty...... It is like a mirror; sometimes calm, sometimes filled with rage, overwhelming, to sail the boat overturned. In my mind, the sea is blue world, is also the cradle of life. Pregnant with many free and small life. The sea is so mysterious, so charming!

¡¡¡¡Now the sea has changed. The sea is no longer clear, it becomes muddy and dirty. Washed up on the beach, left is no longer alive and kicking the fish shrimp, instead of the piles of rubbish, but also mixed with a lot of dead fish shrimp, stinking. Why is that? It's all because of us. When people admire the beauty of the seaside, they throw the foul rubbish into the sea. There are also people living on the beach, the toilet drain pipe to the bottom of the sea. What's worse is that the factory waste water flows into the sea in large stocks, and the sea is dyed in a strange color. Led to the birth of a lot of lack of brains, low IQ infants, our next generation - bright eyes [voice tender], the face of the next generation of red, will never see the beautiful blue sea.

¡¡¡¡Someone once did an experiment. He compared a basin of water to the ocean, and dropped a drop of ink into the sea. Immediately, the ink slowly spread out, became shallow and disappeared. The sea water was almost as clean as ever. If the ink kept dropping, the color of the sea would be deeper and darker, and eventually it would become a basin of black water. 6 billion people on the earth produce large quantities of living waste water and industrial pollution every day. Like ink, it has been injected into the clear sea water. It has become a polluted lake.

¡¡¡¡The simplest water pollution definition would be any contamination of water bodies with some pollutant(s) that changes physical,biological,and chemical conditions of any body of water making this water harmful for environment and surrounding ecosystems.

¡¡¡¡Water pollution occurs once too much pollutants (mostly in form of different waste) are discharged directly or indirectly into water bodies.Water pollution does not only cause great environmental damage but is also the leading worldwide cause of deaths and diseases responsible for the deaths of more than 14,000 people each day,mostly in developing countries.

¡¡¡¡Many people are not aware that water pollution is serious problem in almost all parts of the world,and not just in third world countries like some choose to believe.In fact many experts will tell you that reality is completely different than the common belief,and that actually water pollution problem is already out of control.

¡¡¡¡Water pollution problem is in most cases connected with the careless handling of chemical agents,toxins introduced into our water through industrial dumping,and farm runoff.All these factors make our water unsafe to drink.

¡¡¡¡The Marine life environment is a complex system including seawater, sea water content and suspension, seabed sediment and Marine life.The abundant biological resources, mineral resources, chemical resources and power resources of the sea are the indispensable resources of human beings, which are closely related to the survival and development of human beings.

¡¡¡¡The main objective of Marine conservation is to protect Marine life resources so that they are not depleted for sustainable use.Special priority should be given to protecting Marine life that is valuable and endangered.According to the relevant departments of the investigation, due to overfishing, accidental killing of non-target to allow hunting of Marine, coastal tidal flats in the engineering construction, mangrove deforestation, widespread Marine pollution, at least 25 in the world's most valuable fisheries resources exhausted, whales, turtles, manatees and many other Marine animals are in danger of extinction.With the expansion of Marine development, the potential for greater damage to Marine biological resources is expected.

¡¡¡¡"Bumper harvest, bumper harvest!"!" Cried one of the fishermen, happily jumping up like a child. After a while, the full cabin fish alive and kicking, calm sea filled with ing from all sides of the fishermen's laughter.........

¡¡¡¡Now, like this "fish and shrimp full cabin" scene has been very rare. In today's market, is the most mon fish pound at least to dozens of yuan, more serious pollution of the ocean, the ocean resources gradually dried up, seafood production, prices rise, it illustrates this point?

¡¡¡¡In the ocean of natural calamities and man-made misfortunes emerge in an endless stream today, human pollution is often not from the original intention, but it is caused by the unexpected effect. The British Petroleum oil, because the drilling platform explosion, caused by the oil spill in the Gulf of Mexico, to 9900 square kilometers of sea water is seriously polluted, so that tens of thousands of seabirds soaked in oil to move, die in hunger and misery, makes countless fish poisoning death; and the Japanese earthquake and tsunami triggered a nuclear leak the marine pollution is more serious......

¡¡¡¡The sea is so vast that it is because the rivers and streams flow into the Yangtze River and then run into the sea. If we do not solve the pollution problem from the source, then no matter how people clean up the sea, there will always be sewage flowing into the sea, and all the efforts will be futile. Now, streams and streams are often seriously polluted, or they bee places where people dump rubbish or are loaded with pesticide cans. Finding a clear stream in an inhabited area can be very difficult today!

¡¡¡¡In any case, the protection of the oceans can not be achieved by individual forces, and the protection of the oceans depends on the joint efforts of all mankind. I do not want one day in the future, our descendants can only imagine the image of the vast and wide sea.

¡¡¡¡This is not only the wish of a pupil, but also the wish of all mankind, isn't it?

On the beach there grows many palm beach, lying quietly in many shells, conch. A few crabs to climb. Should be against the background of blue sky, the sky the sun, seagulls flying, this beautiful picture of you! What an intoxicated! I feel relaxed and happy.

¡¡¡¡Can be when I saw the sea of a moment, I am disappointed, the mood suddenly changed. Because my eyes of the sea is dark, is muddy, is not angry, is not confident. Some just inferiority. I know that the sea is not so, but people are polluting into this.

¡¡¡¡Now, human beings in order to live, a large number of cutting trees, cut and not planted, how many of the previous tropical rain forest, now is flat, how many trees, now replaced by high-rise buildings. Factory emissions, air pollution, and no trees to release fresh air. And plant emissions of toxic wastewater, so that water in the small fish, shrimp have been poisoned, and the river afloat smelly fish dead bodies and garbage, all this is how terrible ah!

¡¡¡¡The seas and oceans receive the brunt of human waste, whether it is by deliberate dumping or by natural run-off from the land.

¡¡¡¡In fact over 80% of all marine pollution comes from land-based activities and many pollutants are deposited in estuaries and coastal waters. Here the pollutants enter marine food chains, building up their concentrations until they reach toxic levels. It often takes human casualties to alert us to pollution and such was the case in Minimata Bay in Japan when many people died as a result of a pollutant building up in food chains. A factory was discharging waste containing methyl mercury in low concentrations into the sea and as this pollutant passed through food chains it became more concentrated in the tissues of marine organisms until it reached toxic levels.

¡¡¡¡Oceans becoming more acidicThe world's oceans are slowly getting more acidic, say scientists.The researchers from California say the change is taking place in response to higher levels of carbon dioxide in the atmosphere.The lowering of the waters' pH value is not great at the moment but could pose a serious threat to current marine life if it continues, they warn.Ken Caldeira and Michael Wickett, from the Lawrence Livermore National Laboratory, report their concerns in the journal Nature.Increasing use of fossil fuels means more carbon dioxide is going into the air, and most of it will eventually be absorbed by seawater.

¡¡¡¡Once in the water, it reacts to form carbonic acid.Scientists believe that the oceans have already become slightly more acidic over the last century.But these researchers have tried to predict what will happen in the future by combining what we know about the history of the oceans with computer models of climate change."This level of acidity will get much more extreme in the future if we continue releasing CO2 into the atmosphere," said Dr Caldeira."And we predicted amounts of future acidity that exceed anything we saw over the last several hundred million years, apart from perhaps after rare catastrophic events such as asteroid impacts."If carbon dioxide release continues unabated, ocean pH could be reduced by as much as 0.77 units, the authors warn.It is not absolutely clear what that means for marine life, however.

¡¡¡¡Most organisms live near the surface, where the greatest pH change would be expected to occur, but deep-ocean lifeforms may be more sensitive to pH changes.Coral reefs and other organisms whose skeletons or shells contain calcium carbonate may be particularly affected, the team speculate. They could find it much more difficult to build these structures in water with a lower pH.In recent years some people have suggested deliberately storing carbon dioxide from power stations in the deep ocean as a way of curbing global warming.But Dr Caldeira said that such a strategy should now be re-considered."Previously, most experts had looked at ocean absorption of carbon dioxide as a good thing - because in releasing CO2 into the atmosphere we warm the planet; and when CO2 is absorbed by the ocean, it reduces the amount of greenhouse warming.

¡¡¡¡Everyone knows that there are 9.6 million square kilometers of land in our country, but who knows, how much of the sea area belong to our country?Let me tell you!It's 3 million square kilometers.

¡¡¡¡One might ask: since there is so much land, there should be a lot of sea creatures.Yes, I have about 10% of the world's Marine life.These sea creatures are like our brothers and sisters.But our brothers and sisters are slowly disappearing. Why?Because we humans.

¡¡¡¡You should know the baiji dolphin.It is so many countries around the world, but the Chinese some rare animals, living in the middle and lower reaches of the Yangtze river, because of we human beings have built chemical plant wastewater discharged by the precocious the pollution, the quality of the water in the Yangtze river and living garbage......The ruthless destroyed their habitat, rubbish make them homeless, can't adjust the very serious environmental contamination, in the end, the national level to protect animals, this ancient and beautiful animal, the number of baiji is regarded as "living fossil" less than 5% of the giant panda.

¡¡¡¡The Tibetan antelope is a protected wild animal at the national level, and 99% of the world's Tibetan antelope live on a plateau more than 4,500 meters above sea level in western China.The Tibetan antelope is light and soft and warm.The shawl made from it became a fashion for the rich in the west in the 1990s.However, the Tibetan antelope must be killed if it is to be collected.The number of surviving Tibetan antelopes is now only 15, 000 -- 100, 000, a tenth of a century ago.If they continue to destroy them, no protection will be taken, and the Tibetan antelope will be extinct in 20 years.

¡¡¡¡These two animals are not Marine animals, but I think if we continue to destroy the environment and kill animals, Marine life will also be at risk.For example, the largest and heaviest blue whale in Marine life, the number of blue whales is decreasing rapidly due to the indiscriminate hunting and the destruction of the environment.
