保护海洋英语演讲稿
水是生命之源 , 假如地球上没有水 , 那么地球母亲就不会孕育出
我们人类的子孙万代。 因为最早的原始生命首先是在海洋中孕育形成 ,
逐渐扩展到陆地上。下面是为大家收集关于保护海洋的英语演讲稿,
欢迎借鉴参考。
Sea pollution is being an increasing problem for our pla
and we have a responsibility to reduce sea pollution.
I need to describe the problem. Our ship currently dumps
all its rubbish into the sea.It'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 es 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 bee 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 our
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.
