3、le 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, a

7、d 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 s

8、ure you will feel the power of science is so magical.2關于海洋污染的英語演講稿Pollution in the ocean is a major problem that is affecting the ocean and the rest of the Earth, too. Pollution in the ocean directly affects ocean organisms and indirectly affects human health and resources. Oil spills, toxic wastes,

9、 and dumping of other harmful materials are all major sources of pollution in the ocean. People should learn more about these because if people know more about pollution in the ocean, then they will know more about how to stop pollution.What are toxic wastes?Toxic wastes are poisonous materials that

10、 are being dumped into the ocean. They harm many plants and animals in the ocean and have a huge impact on our health. Toxic waste is the most harmful form of pollution to sea life and humans.
