高分英语作文1:Protect the ocean

The oceans are becoming more and more acidic, and the world's oceans are slowly becoming acidic, scientists say, and researchers from California say the change is due to increased levels of carbon dioxide in the atmosphere. Researchers from Lawrence Livermore National laboratory report their concerns in the journal Nature: the increasing use of fossil fuels means more carbon dioxide goes into the air, and once in water, most of it Carbon dioxide will eventually be absorbed by seawater, and scientists believe that the ocean has become slightly acidic over the past century, but these researchers are trying to predict what will happen in the future by combining our understanding of ocean history with computer models of climate change. "This level of acidity will become more extreme" in the future, if we continue to increase Gas releases carbon dioxide, "Dr.

caldella said." we predict that acidity in the future will exceed anything we've seen in the last few hundred million years, except after rare catastrophic events such as asteroid impacts. "If carbon dioxide emissions continue to increase, the authors warn that the pH of the ocean may drop to units, but it's not entirely clear that this is true What does marine life mean, because most organisms live near the surface of the sea, and the maximum pH change is expected, but deep-sea organisms may be more sensitive to changes in pH. the biological calcium carbonate contained in coral reefs and other bones or shells may be particularly affected, and the team speculates that they may find it difficult to construct these structures in water with low PHN Much more.

In recent years, it has been suggested that carbon dioxide from power stations be stored in the deep sea as a way to curb global warming, but Dr. caldera said such a strategy should now be reconsidered. "In the past, most experts regarded the absorption of carbon dioxide by the ocean as a good thing, because when we release carbon dioxide into the atmosphere, we warm the earth When absorbed by the ocean, it reduces the greenhouse effect.

海洋变得越来越酸世界上的海洋正在慢慢变酸,科学家说,来自加利福尼亚的研究人员说,这种变化是由于大气中二氧化碳含量的增加而发生的。他们警告说,海水pH值的下降目前并不严重,但如果持续下去,可能会对目前的海洋生物构成严重威胁,来自劳伦斯利弗莫尔国家实验室的研究人员在《自然》杂志上发表了他们的担忧:化石燃料的日益使用意味着更多的二氧化碳进入空气中,一旦进入水中,大部分二氧化碳最终会被海水吸收,科学家们相信,在过去的世纪里,海洋的酸性已经稍微变强了,但是这些研究人员试图通过将我们对海洋历史的了解与气候变化的计算机模型相结合来预测未来会发生什么,“这种酸性水平将变得更加极端“未来,如果我们继续向大气释放二氧化碳,”卡尔代拉博士说,“我们预测未来的酸度将超过我们在过去数亿年中所看到的任何数值,除了在小行星撞击等罕见的灾难性事件之后,”如果二氧化碳的释放继续有增无减,作者警告说,海洋的pH值可能会降低到单位,但目前还不完全清楚这对海洋生物意味着什么,因为大多数生物都生活在海面附近,预计会发生最大的pH值变化,但深海生物对pH值的变化可能更敏感珊瑚礁和其他骨骼或贝壳中含有的生物碳酸钙可能会受到特别大的影响,研究小组推测,他们可能会发现在PHN较低的水中建造这些结构要困难得多。近年来,有人建议有意将发电站的二氧化碳储存在深海中,作为遏制全球变暖的一种方式,但卡尔德拉博士说,这样的策略现在应该重新考虑”以前,大多数专家都把海洋吸收二氧化碳看作是件好事,因为在向大气中释放二氧化碳时,我们使地球变暖,当二氧化碳被海洋吸收时,它减少了温室效应。

万能作文模板2:保护海洋

The marine environment is a complex system resistant to hydrolysis and suspended solids, seabed sediments and marine organisms in water and sea water. The ocean is rich in biological resources, mineral resources, chemical resources and electric power resources. It is an indispensable treasure house of human resources, which is closely related to human survival and development.

At present, the main goal of marine protection is to protect marine living resources, According to the United Nations survey, priority should be given to the protection of precious and extremely endangered marine organisms caused by overfishing, accidental capture and killing of non target organisms to allow hunting of the ocean, construction of coastline, mangrove felling, and large-scale marine pollution. At least the world's most valuable fishery resources are exhausted, and whales, turtles and sea are exhausted Many marine animals, such as cattle, are in danger of extinction. It is estimated that with the expansion of marine development scale, marine biological resources are likely to cause greater damage.

The first task of marine protection rights is to stop the excessive development of organisms, and secondly, to protect the habitats or habitats of marine organisms, especially their migration, spawning and foraging, to avoid the coast, beach, estuary and coral reef Such predators must prevent the harm of heavy metals, pesticides and oil. Organic nutrients such as eutrophication can pollute the ocean, protect the natural regeneration capacity and water purification capacity of marine biological resources, maintain the marine ecological balance, and ensure the sustainable development and utilization of the ocean.

海洋环境是一个在水、海水中耐水解和悬浮固体、海底沉积物和海洋生物的复杂系统,海洋蕴藏着丰富的生物资源、矿产资源、化学资源和电力资源,是人类不可缺少的资源宝库,与人类生存和发展的关系非常密切,当前海洋保护的主要目标是保护海洋生物资源,以免失败,以利于人类的可持续利用,根据联合国调查,优先保护因过度捕捞、意外捕获和杀害非目标生物以允许捕猎海洋、建设海岸线、砍伐红树林、大面积海洋污染等原因造成的珍贵和极度濒危的海洋生物,至少世界上最宝贵的渔业资源枯竭,鲸鱼、海龟、海牛等许多海洋动物面临灭绝的危险,预计随着海洋开发规模的扩大,海洋生物资源很可能造成更大的破坏,第一个海洋保护权的任务就是制止生物的过度开发其次要保护海洋生物的栖息地或栖息地,特别是它们的迁徙、产卵、觅食,避开海岸、滩涂、河口、珊瑚礁等掠食者,必须防止重金属、农药、油类物质的危害,有机易产生的营养物质如富营养化对海洋的污染,保护了海洋生物资源的自然再生能力和净水能力,维护了海洋生态平衡,保证了人类对海洋的可持续开发利用。

Marine environment is a complex system of water and sea water resistant to hydrolysis and suspended solids, seabed sediments and marine organisms. It contains abundant marine biological resources, mineral resources, chemical resources and electric power resources. It is an indispensable resource treasure house for human beings, which is closely related to the survival and development of human beings.

At present, the main goal of marine protection is to protect marine organisms According to the United Nations survey, due to overfishing, accidental capture and killing of non target organisms, at least the world's most valuable fishery resources have been exhausted Fish, turtles, manatees and many other marine animals are at risk of extinction. With the expansion of marine development scale, marine living resources may cause greater damage. The first task of the right of marine protection is to stop the over exploitation of marine living resources, and the second is to protect the habitats or habitats of marine organisms, especially their migration, spawning and foraging, avoiding predators such as coasts, beaches, estuaries and coral reefs.

It is necessary to prevent marine pollution caused by heavy metals, pesticides, oil and organic matters, which are easy to produce nutrients, and protect marine organisms The natural regeneration ability of resources and water purification capacity are strong, and the marine ecological balance is maintained to ensure the sustainable development and utilization of the ocean.
