Should the Sea Be exploited
Hello, everyone, I am fairly honored to illustrate the views concerning whether the sea should be exploited on behalf of our team. We are opposed to exploiting the sea and the reasons are as follows.
It is known that the sea is the cradle of life who gave birth to life on the earth. However, owing to human being’s over exploitation, the sea is being severely destroyed at an alarming speed now, with many species dying out and piles of rubbish ---plastic floating everywhere.Worse still, due to illegal hunt and overfishing, the number of whales has sharply decreased in the past five years. It is we human beings that put various creatures on the verge of distinction,such as colorful coals.
There is a famous saying that too much water drowned the miller, which shows the importance of keeping the balance of the ocean ecology . So let’s do our bit to take action right now.
巩固练习参考范文:
Dear Jim,
How is everything going there Recently. I just have finished my subject which is about Ocean Conservancy. It is said that our oceans are facing unprecedented pollution.Abundant marine resources are being depleted,and artificial waste kills countless ocean lives every year.
There are two main reasons for these problems. First of all, the discharge of untreated industrial waste water from coastal industries is the main cause of serious pollution of coastal marine water quality. What’s worse, overfishing in the fishing industry destroys the ocean life chain. Therefore, I think the government should strengthen the supervision of the coastal enterprises and set up the closed season to ensure the fish breeding.
Yours,
Li Hua
注： conservancy n.保护 unprecedented adj.史无前例的 deplete v.耗尽；大量减少 supervision n.监督；管理
