海洋温度对珊瑚繁殖的影响,珊瑚的破坏情况

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,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 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.When toxic waste harms an organism,it can quickly be passed along the food chain and may eventually end up being our seafood.In the food chain,one toxic organism gets eaten by another,larger animal,which gets eaten by another animal,and can end up being our seafood.Toxic waste gets into seas and oceans by the leaking of landfills,dumps,mines,and farms.Farm chemicals and heavy metals from factories can have a very harmful effect on marine life and humans.
Many fishermen believe that the toxic chemicals in the ocean are killing much of the fish population.One of the most harmful chemicals in the ocean is lead.Lead can cause many health problems.It can damage the brain,kidneys,and reproductive system.Lead can also cause birth defects for people.It has been shown to cause low IQ scores,slow growth,and hearing problems for small children.House and car paint and manufacturing lead batteries,fishing lures,certain parts of bullets,some ceramic ware,water pipes,and fixtures all give off lead.
Many things found in the ocean may cause seafood to be dangerous to human health.The effect on humans from contaminated seafood may include birth defects and nervous system damage.Medical waste found in the ocean is being tested to see if swimmers have a chance of developing Hepatitis or AIDS.Other waste has been known to cause viral and bacterial diseases.This type of pollution can be stopped by watching what pollution we are letting into the ocean.People are trying to decrease the amount of waste in the oceans by recycling as much garbage as they can so there is a smaller amount of very harmful materials in the ocean.
Boating Pollution Prevention Tips
Whenever someone takes their boat onto the water for a ride,it is creating pollution that can be very harmful to the sea life.Boating pollution is the pollution that comes from the boat’s engine when it is running,and it pollutes the water,killing animals with the chemicals in the exhaust from the engine.The engine gives off excess gasoline,which pollutes the waters and ends up killing the animals.In order to make as little pollution as possible,what everyone can do to help is:
Only turn a boat engine on all the way when you need to.
Don’t take your boat out into the water if you don’t need to.
Be sure to store and transport gasoline in places where there isn’t any direct sunlight because the gasoline will evaporate,and all of the gases that have been evaporated will pollute the air.
Every year,buy new or cleaner marine engines for your boats.
Garbage Dumping
Garbage dumping is the dumping of harmful materials into the ocean like human waste,ground-up garbage,water from bathing,and plastics.Most of the waste that has been dumped into the ocean in the early 1990’s is still there today.One main cause of garbage dumping occurs when sewage pipes share their space with storm water drains.Rainfall causes the sewage pipes to overflow and the sewage waste mixes with the storm water drain,which flows into another water source such as a lake or river.After that,the garbage pollutes the ocean,kills plants and animals in the water (for example,the plastic rings that are around pop cans can get around an animal’s neck,causing it to suffocate),and makes the water dirty.

工业排放

空气中CO₂的含量增多,会导致海水酸度增强.
原因：
CO₂+H₂O＝H₂CO₃

你知道,过滤的方式只能除去不溶性杂质,而可溶性杂质不能除去.

A Polluted Environment
Environmental pollution is a serious social problem. It poses a terrible threat to men’s health.
The atmosphere is filthy. The air is thick with dust and burnt oil. Da...

首先宣传污染的可怕,污染的预防方法 然后就是针对预防方法做出具体的布置和实施方法 设立奖惩措施,加大治理力度 同时要派专人负责此项目,设立配合人员

目前海洋污染主要是局部海域出现“赤潮”,造成大量鱼虾死亡.你认为形成“赤潮”的主要原因是 含磷化肥在大量使用 .而养殖的鱼虾大量死亡的直接原因是 溶解氧剧降

海洋污染的现状,概括来讲,主要有：（污染源）多,（污染范围）广,（污染程度）重.

错

洋流对海洋污染的影响是有利于污染物的扩散，加快净化速度，但扩大了污染范围。因此洋流对海洋污染有利也有害。

好的影响是可以加快净化速度,但是不好的影响就是也会扩大污染面积.
海洋环境的保护需要对洋流的流向做了解,以便发生污染事故是及时采取措施治理

海洋污染的现状,概括来讲,主要有：（污染源）多,（污染范围）广,（污染程度）重.
望采纳.

分析这类题目首先要看是不合理的,因此B选项加强近海捕捞就等于竭泽而渔,所以B选项很不合适.下次如果拿不准的话可以先从题干给出的措辞入手.

世界卫生组织(WHO)报导:世界20个污染最严重的城市,中国占16个~经济损失八千万人民币(保守估计)~导致每年三十五万人提前死亡~~(有何方法?)(拒绝外国工业?)(可是利益上会受损)(健康重要’还是财富重要?)~请大家三思~
据报导:五湖三江都被污染了~~因为招揽连外国他们自己都不敢要的工业’(工业废水’有的很毒)~~唉!我们只管眼前有钱赚~(下一代可怜了)~~祝福大家!

不要让海洋再哭泣

通过 废物注入海洋,通过 生物的形式注入海洋,还有通过管道 排放废水刀海洋等.

When referring to marine pollution emissions to the ocean of human waste or dirt,so that water quality is deteriorating,and make life in the ocean of biological damage,but also harm people's activities at sea,endangering human health.
