保护海洋的英语演讲稿
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 '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!

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.
As a consequence 649 people died from eating fish and shellfish contaminated with mercury and 3500 people suffered from mercury poisoning.

Future marine
Know you today from the 20xx, let me do a return tour, you tour in 2030 with the "Ocean", I think you must be harvested. As we all know, oceans of the Earth's seven tenths, very serious marine pollution in 20xx, but in 2030, due to advanced science and technology, "decontamination robot" has become the bane of marine pollution, so, when there is no pollution in the ocean. Now, I take you first "multi-functional reception", and replace "changes in the marine location device", it all took us off to another world. Today's oceans, is home to human beings, 50 percent of people worldwide live in the ocean, you will find it very curious about how to survive in the ocean? Fact Well, Sea World, where there is an "oxygen control room," Oxygen produced from here, through the "oxygen cylinder" sent to every corner of Ocean, people breathing in fresh oxygen, emit carbon dioxide, and then by the "oxygen control room" to receive, but also to create such a cycle of oxygen ... ....
Harbour fish is strange, since the sea water into fresh water, the fish learned human language, but also to talk with people it can be fun! You to the front of a large group of fish, fish said: "Good morning!" Fish will speak English, I am really not believe it. Listen to my introduction to you on the residential areas. Although before you see is a blank, but people live here. The sea and land were not the same person, they food is simple, a "simple food Dan" can be over 100 days, so they are very relaxed. Live it? To four "sea" as their home, think of where to sleep on where to sleep, carefree.
Then, you visit the Royal Palace, Park ... ... must have felt very grand, magnificent it! Perhaps you worry about, so many people living in the seabed, the environment will not occur the problem? Not. Harbour achieved without factory, but there are production. And no worse than the production of the land, because we row down the waste land, water, through the "decontamination robot" "pass" "make the robot" for processing, making available all kinds of things ... ... strange, wonderful sea world tour finished, how? I am sure you will feel the power of science is so magical.
