Ocean————The Hope of The 21st Century

Do you know ？ When the astronauts look back to our planet ， they discovered that the earth is a water polo in the universe 。 For thousands of years , we love the sea ， but we also feel full of fear . Today ， due to the rapid development of science and technology ， human is facing a new era of development of ocean . So people say that the 21st century is called the Ocean Century 。

As you know ， the ocean is a cornucopia ， which is rich in oil ， coal ， gas ， etc . But how to exploit ? We need to take a consideration . If we treat ocean as what we did for the land , it maybe dangerous for the ocean . So we need some proper ways to develop the ocean .

So what we should do ？ First ， I think ， we need sustainable exploitation 。 Uncontrolled exploitation is certain to destroy the ocean 。 Just look at what we did for the land , you may know the importance . Second ， try not to destroy the original environment of the ocean 。 The marine ecosystem has close internal relations . So the destruction of a small portion will cause irreparable results 。 The oil spill of the Gulf of Mexico gave us a wake-up call . Third ， everyone in the earth needs to protect it 。 What we can do for the ocean may be just a little , but strength in numbers . If everyone does not throw garbage into the sea , the sea—level fall may come true 。

The 21st is called Ocean Century , but also called Ocean Protection Century 。
