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 .
