Marine environment 700 words.

The ocean is rich in oil and natural gas resources, and people erect high drilling platforms on the sea surface to continuously transport oil and natural gas from the seabed to the land. There are countless fish, shrimp, crabs and shellfish in the ocean. Since ancient times, people living on the seashore and islands have lived by the sea. Every fishing season is a fisherman's harvest season, and the fishing boats that go out to sea will always return with full loads. The ocean is really a "blue cornucopia" Let's share it with you. Welcome to reading.

I am a little turtle living in the sea. In recent years, I have become more and more distressed because the sea where I live has changed. People have built farmhouses, paper mills and steel mills by the sea. Many tall buildings have been built, which makes our family very restless.

Once, we went out to play with friends. Suddenly, with a scream, Linlin turned around and Linlin disappeared out of thin air. Linlin's good friend, where are you? At this moment, Linlin stretched out his arm from under a pile of rubbish and desperately asked for help. Jumping and Yue Yue quickly shouted to everyone: Quick, save Linlin! People still don't know where Linlin is. He pointed sharply at the garbage mountain and said, "That's Linlin!" As soon as the voice fell, I saw some filthy rubbish littering the sky. Everyone and I were shocked and jumped up and down in a panic. I can only hear everyone crying. A few days later, people had to push their luck to throw dirty water and smelly water into the sea, and garbage was also thrown into the sea. Some people even throw TV sets to the bottom of the sea.

The life of underwater animals was disrupted, and the underwater biology conference was held soon. Our head shark said, "My companion was also killed by garbage. The bottom of the sea is full of sewage, and many marine species are infected with viruses and sick. How will we live in the future? I said: my companion was also killed, and the shell of one of my companions was smashed. Now the children of the tribe are too scared to come out at home. Haima also said: "My horn was smashed off a year ago, and now everyone calls me' one-horned monster'. After that, I cried bitterly ... at this time, everyone was telling the sins of mankind. Finally, we decided to write a letter to people and hang it on the hook of fishing.

The content of the letter is roughly, please don't destroy the ocean. Your destruction of the ocean is a complete suicide. Wake up mankind! People caught in the letter suddenly realized, began to reflect, and began to pay attention to the protection of the ocean. They build garbage trucks and work in the sea every day. A marine protection inspection team has also been set up to arrest and severely punish those who ignore marine protection.

After a period of rectification, the sea is still full of vitality, and we began to move forward on the sea again, and the people at sea gave out bursts of laughter.

The ocean accounts for about two-thirds of the total area of the earth. There are all kinds of creatures in the ocean, and there are other rich resources. We live on an island, and the sea has increased a lot of economic income for fishermen on the island, and also brought a lot of convenience and fun to islanders. At the same time, it also attracts many foreign tourists to visit and explore the island. In particular, the discovery and archaeology of "Nan 'ao No.1" have attracted the attention at home and abroad and even the whole world. As islanders, we are very proud.

However, in recent decades, human beings have no scruples about the pollution of the ocean, dumping pollutants and harmful substances into the ocean at will, making some marine life on the verge of extinction, and exploiting a large number of resources under the seabed, resulting in a large number of precious fish species in the ocean dying, and even some have become extinct.

I remember when I was only four or five years old, I often went swimming in the sea with my father in hot summer. But the year before last, I didn't know that people who had no sense of public morality actually dumped some daily garbage on the beach. After the waves washed away, the garbage naturally went to the sea. I saw disgusting rubbish floating on the sea. Neither my father nor I wanted to swim, so we shook our heads with a sigh and went home.

With the continuous growth of population, people fish a lot, and there are fewer and fewer fish. Fish is in short supply and the price is getting more and more expensive. People complain that it is difficult to eat fish. It was not until the state issued a ban on the sea, regularly banned the sea every year, and regularly organized relevant units to stock fry in the sea that the number of fish gradually increased. It is gratifying that some endangered species have been better propagated.

Water is the source of life. The ocean occupies such a large area of the earth, and it also brings so many benefits to people. Everyone should join hands to protect the ocean. Protecting the ocean means protecting the earth, which means protecting our home. Let the marine environment become more magnificent, and let the ocean better benefit our future generations!

The endless sea gives people hope, beauty and warm maternal love.

The sea is like a poem, jumping nimbly; Like a painting, rich in connotation; It is also like a symphony, vast and surging ... it is sometimes as calm as a mirror; Sometimes the angry and turbulent tide will overturn the sailboat. In my mind, the sea is a blue world and the cradle of life. Gave birth to many free little lives. The sea is so mysterious and charming!

Now, the sea has changed. The sea is no longer clear and becomes muddy and dirty. The sea washed up on the beach, leaving behind piles of garbage instead of lively fish and shrimp, mixed with many tragic fish and shrimp, emitting a stench. Why is this? It's all because of us humans. Some people enjoy the beautiful scenery at the seaside and throw stinking garbage into the sea. And people who live by the sea connect the drain pipe of the toilet to the bottom of the sea. To make matters worse, the waste water discharged from factories flowed into the sea in large streams, which dyed the sea water a strange color. As a result, many babies with brain deficiency and low IQ were born, and our next generation-the next generation with bright eyes, immature voice and red face-will never see the beautiful and charming blue ocean again.

Someone once did an experiment. He compared a basin of clear water to the sea, and then dropped a drop of ink into it. Suddenly, the ink slowly dispersed, shallowed and disappeared, and the "sea water" was almost as clean as the original; The ink kept dripping. "The color of the sea water will get deeper and deeper, and finally it will become a basin of black water." 6 billion people on the earth produce a lot of domestic wastewater and industrial pollution every day, just like ink, which is injected into the original clear seawater and soon becomes a pool of sewage.

For our human health, for our future generations to see the beautiful and charming blue ocean. Let's act at once, love the ocean like life, and love this blue home with humanity.

In the blue ocean, there lived a little turtle. He was born and raised in Sri Lanka, and he never wanted to leave this beautiful home. But one day, disaster befalls him. ...

"Sell fish, sell fish ..." Yes, this is the cry of selling fish. A group of dark-skinned and strong people came to this ocean. They took a boat and tried their best to throw the fishing net into the sea. The little turtle was playing with his friend, but before he could escape, he was covered by a fishing net.

He was taken to a fish market. A rich man came here to buy fish and suddenly saw this turtle. The little turtle looked at him sadly. The rich man thought he was very spiritual and bought him.

After the rich man took him home, his daughter became friends with the little turtle. A few months later, the rich man wanted to fill up the sea where the little turtle once lived and build a big apartment to make money. When the little turtle heard the news, she began to cry. The crying woke up her daughter. When my daughter saw it, I didn't expect the little turtle to talk: "Boo hoo … you bad humans are going to fill up the sea. I hate you. I will never play with you again! " My daughter felt particularly uncomfortable when she saw the little turtle crying like this. She ran to her father's bedroom and explained the situation to him. Dad usually pays the most attention to his daughter's mood, especially doting on her. Seeing her like this, his heart immediately softened and he promised again and again.

But the little turtle is in pain. After the rich man knew that their turtle could talk, he thought of selling it to him at a high price, and people came to their house in an endless stream. It is said that the tortoise monster, the price doubled. Finally, someone paid 65,438+10,000 yuan to buy this strange turtle, and even the director of the country came to join in the fun and told him about it-the chairman immediately listed this little turtle in National No.1 Middle School. Little turtle's mother knows this and is proud of her son, because it is her son who saved the whole ocean. Finally, people decided not to destroy the ocean and set the little turtle free. Finally, the little turtle family is reunited!

It was a turtle that saved the whole ocean and all the living things in it. We humans should also protect the ocean. Come on, let's create a better tomorrow!

Today is the fourth grade. It's cloudy, but it seldom rains. According to the plan, we drove to Shitang town early in the morning, ready to go fishing by boat.

Not far from the seaside, a salty sea breeze blew to me, and I took a deep breath of seawater. In a short time, an endless sea of gangsters appeared in front of me, which was completely different from the blue sea I imagined. The speedboat took us from the shore to the fishing boat moored in the sea. This ship is really big. It is divided into upper, middle and lower layers. The ground floor is the motor and some mechanical equipment. The middle floor is the place where the crew rest, cast nets and collect nets. The upper floor is the cockpit and observation deck.

The boat went forward for a while, and the boatman announced, "Ready to cast a net." At first, I thought I cast my own net, but beyond my imagination, it was all mechanized. I cast my net at the press of a button, which was a bit disappointing. After the net was cast, I came to the cockpit and experienced the feeling of steering. At that moment, I felt mighty, as if I were a captain, sailing on a big ship and going wherever I wanted. About half an hour later, the gateway stopped, so I hurried to see it. There are lively little yellow croaker, jumping fish, octopus with claws, and shrimp and crab waving small pliers at me. They seem to be protesting to me that they should not be allowed to leave their homes. Although we harvested a lot of seafood, none of them were big. I threw the smaller fish, shrimps and crabs back into the sea and let them return to their mother's arms.

After fishing, we returned to the shore by speedboat. This experience made me happy and worried. I'm glad to experience how to fish first-hand, but I'm worried when I hear adults say that "there are fewer and fewer fish to catch offshore". This is all because people put forward excessive demands on nature. Fortunately, now I have realized the seriousness and started to protect it. For example, there is a fishing moratorium every year, which is to give marine life a growth cycle. We are all members of nature, and it is everyone's responsibility to protect the ocean.
